Al2O3 Dispersion Strengthened Copper Alloy Produced through Internal Oxidation and its Microstructure and Property

  • 摘要: 采用内氧化法用雾化铜铝合金粉制备出了铝含量(质量分数)分别为0.15%、0.25%、0.35%的3种氧化铝弥散强化铜合金。研究了Al2O3弥散强化铜合金的组织与性能。结果表明,弥散铜合金的晶粒细小,晶粒大小在0.2~1μm之间;内氧化工艺生成的细小氧化铝质点在晶粒内部呈弥散分布,其平均直径小于20 nm。0.35%Al含量的弥散强化铜合金抗拉强度为600 MPa,电导率为83%IACS,满足了CuCrZr电阻焊电极的要求,可以作为CuCrZr电阻焊电极的替代材料。
    Abstract: Series of aluminum oxide dispersion strengthened copper alloy(ODSC) containing 0.15%、0.25% and 0.35% Al(wt%) are produced from atomized Cu-Al powder through internal oxidation.Tensile strength and conductivity of the copper alloy with 0.35% Al are 600MPa,83% IACS respectively,meeting the requirement for electrode in resistance welding,as a substitute for CuCrZr electrode.The microstructure and property of the alloy is researched.The result shows that the grain of the ODSC alloy is very small with a size between 0.2~1.0μm.The fine Al2O33 particle is distributed dispersedly in grains.Its average diameter is less than 20 nanometer.
