最近十年来,人们尽了很大努力来研究铝合金的应力腐蚀裂纹生长动力学.同时,出版了很多着重论述氢在铝合金的应力腐蚀开裂机理中的作用的刊物.但在这一时期,未研究裂纹产生的动力学,这可能是由于难以充分确定裂纹产生阶段终点的缘故.而这种研究是很有用处的,因为所获得的数据可以用于研究氢在裂纹产生过程中的作用,从而为应力腐蚀开裂的满意的氢脆模型的综合研究进一步提供输入信号.
In the last decade, great efforts have been made to study the growth kinetics of stress corrosion cracking in aluminum alloys and many publications have been published that highlight the role of hydrogen in the stress corrosion cracking mechanism of aluminum alloys. However, during this period, The kinetics of crack initiation have not been studied, probably because it is difficult to fully determine the end of the crack generation stage, which is useful because the data obtained can be used to study the role of hydrogen in crack initiation, Thus further providing an input signal for a comprehensive study of satisfactory hydrogen embrittlement models for stress corrosion cracking.
