一、黄铜应力腐蚀开裂(SCC)中脱锌的作用及机理黄铜的应力腐蚀开裂(SCC)一直受到研究者的高度重视,不仅仅因为黄铜本身(特别是含锌量小于34%的α黄铜)在工业和国防上应用广泛,而且作为SCC体系,它是高塑性合金在特定环境中变“脆”的典型例证。无论追朔到人类认识SCC的开始,还是回顾SCC机理的研究过程,大量文献资料均以黄铜为具有代表性的研究对象。黄铜是
First, the role and mechanism of dezincification in the SCC SCC has been highly valued by researchers, not only because of the brass itself (especially the zinc content less than 34% α brass) is widely used in industry and defense, and as a SCC system, it is a typical example of high-plasticity alloys that are “brittle” in specific environments. Whether tracing back to the beginning of human cognition of SCC or reviewing the research process of SCC mechanism, a great deal of literature is based on brass as the representative research object. Brass is
