本文依据单向拉伸、纯扭转及单向压缩三个简单试验的测试结果,绘制了LY12、30 CrMnSi、20钢三种金属材料的变形极限曲线。本文的结果对相应材料的实际工艺设计有很好的指导意义。
Based on the test results of three simple tests such as uniaxial stretching, pure torsion and unidirectional compression, the deformation limit curves of LY12, 30CrMnSi and 20 steel were drawn. The results of this article have good guiding significance for the actual process design of the corresponding materials.
