摘要

摘要: 通过爆炸焊接法制备TA2/3A21/AZ31B三层复合板,利用光学显微镜(OM)、扫描电镜(SEM)、能谱仪(EDS)和万能试验机对复合材料的界面、金相组织和力学性能进行测试与分析。实验结果表明:通过一次爆炸焊接制备的TA2/3A21/AZ31B复合材料,其抗拉强度约为303 MPa,屈服强度约为233 MPa,断后伸长率约为9.7%;在钛/铝界面与铝/镁界面均形成爆炸焊接特有的波状结构,界面处分别形成了厚度约5 μm的Ti-Al扩散层和30 μm的Al-Mg扩散层,其剪切强度分别为132.6 MPa和116.3 MPa。与TA2/AZ31B复合材料相比较,该复合材料的力学性能有较大提升。

Abstract: TA2/3A21/AZ31B three-layer composite plate is prepared by explosive welding. The interface, microstructure and mechanical properties of the composite are tested and analyzed by optical microscope (OM), scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and universal testing machine. The experimental results show that the tensile strength, yield strength and elongation after fracture of the TA2/3A21/AZ31B composite prepared by one-time explosive welding are about 303 MPa, 233 MPa and 9.7%, respectively. The special wavy structures from explosive welding are formed at the titanium/aluminum and aluminum/magnesium interfaces. The thickness of Ti-Al diffusion layer at the titanium/aluminum interface is about 5 μm, and the thickness of the Al-Mg diffusion layer at the aluminum/magnesium interface is about 30 μm. The shear strengths of the Ti-Al and Al-Mg diffusion layers are 132.6 MPa and 116.3 MPa, respectively. Compared with TA2/AZ31B composite, mechanical property of the TA2/3A21/AZ31B composite is greatly improved.
