摘要： 本文用“平面应变转轴压缩试验”的方法研究和确定了不同塑性变形路径下α黄铜加工各向异性的加载函数。结果表明，本试验方法对研究大塑性形变下的加载函数很有成效。对α黄铜，混合模型加载函数在不同变形路径下均能成立。

Abstract: By using a new testing method "Plane Strain Compress in Different Orientations", the authors studied the anisotropic hardening effect of α-Brass subjected to several plastic strain paths and determied the loading function of composite model. The conclution shows that this testing method is available in study of large plastic deformation and that the function of composite model for α-Brass subjected to different straein paths is always suitable.

Key words: 变形路径, 各向异性强化, 混合模型, 加载函数
