摘　　要：扭转冷作硬化技术，能产生充分的塑性变形，从而使试件后继屈服极限和极限载荷比拉仲冷作硬化有大幅度提高。本文从试验研究和理论分析两个方面深入研究了这一问题，引出了有益的结果。On the basis of experimental and theoretical analyses, torsion cold--work hardening technique is studied. It is showed that by this technique we can get much higher yielding limit successor and ultimate strength than by tension cold --work hardening.
