摘　　要：金属材料的冷成形会产生加工硬化现象。该现象会对材料性能造成影响。文章通过对国际国内常用标准中受压元件的冷成形方式及变形率限制等相关规定进行对比,浅析了不同标准中相关规定的异同性,并对材料冷成形时导致其性能改变的主要控制因素、恢复材料性能的必要性以及恢复材料性能的热处理方式等进行了讨论,希望能够加深技术人员对这方面知识的理解,以便能够正确应用,从而保证受压元件材料的使用性能,以满足工程需要。Cold forming of metallic materials may result in work hardening which may affect the material properties.By comparing the cold forming methods and deformation rate limitations of pressure components in common international and domestic standards,this paper analyzes the similarities and differences of the relevant provisions in different standards.It also discusses the major control factors leading to the change of material properties during cold forming,the necessity of restoring material properties,and the heat treatment modes for restoring material properties.It is expected to enhance the understanding of technical personnel in this area so that they can apply such knowledge properly so as to ensure the operational performance of pressure component materials to meet engineering needs.
