弥散铜材料的高温本构方程

Constitutive equation for hot deformation of aluminum oxide dispersion strengthened copper

弥散铜是一种新型的粉末体电极材料 ,在加工制备过程中其变形行为会不同于致密体 .针对粉末体材料的变形特性 ,提出了弥散铜的高温本构方程的数学模型 ,并通过大量的热模拟压缩实验 。

The aluminum oxide dispersion strengthened copper (ODSC) is a new type of electrode, and it is deferent from other materials for it is porous. Based on a large number of experimental data, the constitutive equation for hot deformation of ODSC has been developed. [
