摘要
深冷处理对提高金属材料的强度、硬度、耐磨性和尺寸稳定性等力学性能能够起到积极作用,因而广受关注。针对焊接构件中普遍存在的焊接接头软化问题,综合现有文献资料,总结了采用深冷处理工艺来提高焊接接头力学性能新方法的国内外研究现状。
Deep cryogenic treatment attracts much attention in wide fields,since it helps to improve the mechanical performance of some metal,such as strength,hardness,abrasive resistance and dimension stability.The lower of mechanical properties generally exists in welding joint.Based on a review of existing literature,this paper summarized the new methods of through deep cryogenic treatment to improve the welding joint mechanical properties.
