Abstract:
Ag and Cu are widely used in key fields such as smart electronics, wearable devices, and healthcare due to their excellent high electrical and thermal conductivity (HETC) properties. The laser powder bed fusion (LPBF) technology is an innovative technology for high-precision manufacturing of dissimilar metals, which can expand the application of Ag-Cu in the emerging high-tech fields. In this study, we have pioneered the successful fabrication of Ag7.5Cu/Cu10Sn/Ag7.5Cu dissimilar metal samples without macroscopic defects using LPBF technology. The effect of microstructure on microhardness of the Ag7.5-Cu/Cu10Sn (A/C) and Cu10Sn/Ag7.5Cu (C/A) interfaces is investigated. The results show that the high thermal conductivity substrate promotes the molten pool convection in the A/C and C/A interface fusion zones, which can help reduce the porosity and crack defects and improve the interface bonding strength. The gradient grain in the fusion zone prevents the propagation of the microcracks, and facilitates the reduction of crack defects. The isotropy of the interface results in a good combination of macroscopic mechanical properties for the both interfaces. The more intense Marangoni convection at the A/C interface causes a wider fusion zone, which promotes the extensive elemental migration and reduces the macroscopic segregation, and makes the average hardness (183.34HV) in the fusion zone higher than that (134.27HV) at the C/A interface. This study provides theoretical guidance and process reference for the fabrication of HETC dissimilar metals by LPBF.

(FeCoCrNi)88-xMo8WNb3Cx (x=0.25, 0.5, 0.75, 1, 1.5, 2, 2.5) high entropy alloy specimens are prepared by mechanical alloying and additive manufacturing. The formation law of the high entropy alloys is clarified firstly, and then the effects of C content on their microstructures and mechanical properties are further studied. It is found out that the (FeCoCrNi) 88-xMo8WNb3Cx high entropy alloy is composed of FCC and M6C phases when the C content is between 0.25% and 2.50% (mole fraction). With the increase of C content, the compressive strength of the alloy increases and the fracture strain increases at first and then decreases. When the C content is 2.00%, the compressive strength and fracture strain of the alloy are 1 993.4 MPa and 31.5%.

Abstract:
In order to improve the strength of the laser selective melted (SLM) Al-Si-Mg aluminum alloy, a Cu-modified Al-Si-Mg-Zr alloy with high Mg content is fabricated. The processability, microstructure, and mechanical property of the SLM-fabricated Al-Si-Mg-Zr-Cu alloy are systematically studied. The results indicate that the sample exhibits good SLM processability at low laser power (250 W), with a maximum relative density of 99.8%. The microstructure of the alloy is mainly composed of equiaxed grains, with a small amount of columnar grains distributed in the melt pool. The grains contain reticular substructures, and there are nanoscale precipitates exising in the α-Al matrix. When the luse power is 250 W, and the scanning speed is 1 200 mm/s, the microhardness, tensile strength, yield strength, and elongation of the samples are (158 ± 4)HV, (461 ± 25) MPa, (397±32) MPa, and (2.4±0.7)%, respectively. The strength of the SLM-fabricated Al-Si-Mg-Zr-Cu alloy is higher than that of the SLM-fabricated Al-Si-Mg alloy.

Abstract:
The microstructure and tensile properties at room temperature of the laser additive manufacturing Ti55511 titanium alloy are studied, the grain morphologies and crystallographic texture of the as-deposited and heat treated Ti55511 titanium alloy are characterized, and the effects of different annealing temperatures on plasticity of the laser additive manufactured Ti55511 titanium alloy are analyzed. The results indicate that the as-deposited Ti55511 titanium alloy consists of coarse β grains, and the β grains grow alternately in the form of columnar and equiaxed grains, presenting a bamboo-like morphology. In the as-deposited Ti55511 titanium alloy, the α lamellae precipitated from the β matrix provides a large number of interfaces, effectively hindering the movement of dislocations, and allows the alloy having high strength and low plasticity. The yield strength and tensile strength of the alloy annealed at 580 ℃ does not show significant changes, and the elongation increases to a certain extent. When the annealing temperature increases to 620 ℃, the yield strength and tensile strength of the alloy reduce, still greater than 1 000 MPa, and the elongation significantly increases. Therefore, the size and volume fraction of the α grains can be regulated through the annealing heat treatment to improve the strength and toughness balance of the alloy. When the stress is parallel to the Z deposition direction, the yield strength and tensile strength of the specimen are slightly lower than those of the specimen whose stress is perpendicular to the Z deposition direction, and the elongation is significantly higher than that of the specimen whose stress is perpendicular to the Z deposition direction.

Abstract:
AlSi10Mg is the most commonly used aluminum alloy material for additive manufacturing, and its selective laser melting(SLM) products have been widely used in aerospace, automotive industry, and other fields. However, its low strength and plasticity limit its wide application. In this study, 0.3% (mass fraction) nano ZrO2 particles are added to AlSi10Mg alloy atomized powder, and the ZrO2/AlSi10Mg composite is formed by using the SLM technology. The microstructure, tensile property and anisotropic behavior are studied under different heat treatment regimes. The results show that when the annealing temperature rises from 180 ℃ to 270 ℃, the tensile strength decreases continuously, and the elongation first decreases and then increases. After being annealed at 180 ℃ for 2 hours, ZrO2/AlSi10Mg show the best match of strength and plasticity, with the tensile strength of 481.74 MPa, the yield strength of 331.03 MPa, and the elongation of 8.5%. In the process of annealing treatment, the ZrO2 ceramic particles in the composite material maintain a stable structure, and the phase transition is mainly the transition of the AlSi10Mg matrix. In addition, with the increase of annealing temperature, the proportion of large angle grain boundaries in the ZrO2/AlSi10Mg composite material significantly increases, and the average local misorientation decreases. When the ZrO2/AlSi10Mg composite is annealed at 180 ℃ for 2 hours, the tensile strength and elongation in the transverse and longitudinal sections are significantly better than those of the corresponding sections of the AlSi10Mg alloy.

Abstract:
During the working process of fuel plunger pump for aero-engine, the bubbles in the fuel constantly burst with the change of pressure, resulting in the cavitation damage in the bronze layer welded on the bottom of the rotor part. Laser cladding has the advantages such as controllable input energy, dense structure of the cladding layer, and metallurgical bonding with the substrate. In order to reduce the scrap rate of plunger pump rotors, we adopt the laser cladding process to clad the bronze powders prepared by the PREP process on the damaged bronze part, realize the feasibility exploration of the micro-area cladding repair of the cast bronze, and analyze the microstructure and local mechanical property of the cladding layer. The results show that the bronze composition of the cladding layer has basically no burning loss, that the microstructure is a fine dendrite structure, with δ phase(Cu31Sn8) filling the α-Cu dendrite, and that no hot cracks are found in both the cladding layer and bronze substrate. The tensile strength of the cladding layer can reach 313-339 MPa, the elongation can reach 23.5%~24.0%, the hardness is between 118HV0.2-119HV0.2, the coefficient of friction is less than 0.003, the self-corrosion potential is between-0.205-0.230 V and the bonding strength (shear strength) between the cladding layer and bronze substrate is up to 285.8-328.5 MPa. Observation of the sample fracture surface shows that the main fracture mode is the ductile fracture, accompanied with the micropore aggregation fracture, which is caused by the unmelted powders. The analysis shows that the large temperature gradient is the main reason for the formation of the fine dendrite microstructure, and the fine organization structure is the main reason for the good performance of the cladding layer.

Abstract:
The rapid development of radar detection technology has put forward higher requirements for the wave-absorbing properties of thermal components such as engines. The commonly used thermal insulation material yttria-stabilized zirconia oxygen (YSZ) does not have wave-absorbing property, and it is currently used to add wave-absorbing agent in the thermal insulation material to realize its stealth from radar. Based on that, we adopt the additive manufacturing technology to lamellarly distribute the lasamarium iron nitrogen (SmFeN) wave-absorbing agent with different mass ratios and heat-insulating coating material YSZ composites to construct a SmFeN/YSZ composite interface model, whose phase interface perpendicular to the incident electromagnetic wave. The results show that when the SmFeN metal particles and YSZ powders are hierarchically stacked in different ratios, the YSZ/SmFeN heterogeneous interfaces can improve the microwave absorption properties. When the mass ratio of YSZ to SmFeN is 1∶1, the minimum reflection loss value is -54.498 dB and the maximum effective absorption bandwidth is 2.5 GHz.

Abstract:
Magnesium alloys have the characteristics of lightweight, high specific strength, excellent shock absorption and high biocompatibility, which have great potential for the application in the fields such as aviation, aerospace, and biomedical engineering. However, the traditional processing techniques can hardly achieve the preparation of the integrated complex structural components, having seriously restricted the application and popularization of the magnesium alloy parts. Additive manufacturing technology is an advanced technology based on the principle of "discretization+stacking", which is expected to become an important technological approach to solve the problem of complex and difficult machining of thin-walled structural components of the magnesium alloys. In this study, an internal mixer is adopted to mix polymer binder with magnesium alloy powders, and an extrusion machine is employed to prepare wire materials suitable for the fused deposition modeling (FDM) process. The influence of FDM process on the surface morphologies of the green billets is investigated. The orthogonal experiments and data statistics are used to analyze the influence of process level factors on the dimensional accuracy, and the improvement directions for the subsequent sintering processes are proposed.

Abstract:
The hot forging die often has to bear extremely high temperature and strong impact load in the working process, and it is very easy to fail due to wear, corrosion and thermal fatigue. In this study, the process experimentation of H13 hot forging die steel laser cladding technology is studied, and the Inconel 625 high-temperature alloy coating on the surface of H13 die steel is prepared. The microstructure and mechanical properties of the coatings are analyzed. The results show that the change of process parameters has no effect on the phase composition of the coating, and a robust metallurgical bond is established between the cladding layer and the substrate. The optimal microhardness and high-temperature wear resistance are achieved when the laser power is 1 200 W, the scanning speed is 200 mm·min-1, and the powder feeding rate is 1.0 r·min-1.Experimental results from the re-manufacturing of automotive stepped shaft forging dies demonstrate a 28% reduction in wear rate compared with the substrate, and the high-temperature wear resistance of the coating significantly exceeds that of the substrate. The laser-clad Inconel 625 coating has a substantial impact on the service life improvement of the die re-manufacturing.

The unique thermal-mechanical coupling effect of hot isostatic pressing allows it to improve the microstructure and eliminate internal porosity defects in components, which is why it is gradually being used for the organizational performance control of additive manufacturing parts. In this study, a concise overview of the microstructure, defects, and performance of additive by manufactured titanium alloy parts is carried out, as well as the advantages of hot isostatic pressing over traditional heat treatment techniques in terms of microstructure, defects, and performance regulation. The study discovery lays the groundwork for employing hot isostatic pressing technology in the post-treatment procedure of titanium alloy parts produced by additive manufacturing.
