氢对黄铜应力腐蚀开裂敏感性的影响乔利杰，徐荣杰，刘辉，褚武扬，肖纪美（北京科技大学北京１１０８３）１引言对氢致开裂型的应力腐蚀，阴极反应进入金属的氢控制了应力腐蚀裂纹的形核和扩展过程；对阳极溶解型的应力腐蚀，虽然阳极溶解过程控制了应力腐蚀的形核和扩展，但当阴极过程是析氢反应时，进入试样的原子氢有可能起一定作用．在这种条件下，应力、腐蚀、氢这三个因素将同时起作用．到目前为止，关于氢对阳极溶解型?...
Hydrogen could promote stress corrosion cracking (SCC) of a-brass in ammonia solution. For a notched specimen under constant loading, hydrogen shortened the time to SCC fracture particularly upon lower loading. Slow strain rate tensile tests showed that hydrogen reduced both the fracture stress and the time to freture.
