Abstract

Corrosion fatigue crack propagation tests were performed below and above K//I//S//C//C in AlSl 4145 steel heat treated to 1230 MN/m**2 and 0. 1N H//2SO//4 system with particular referece to effects of frequency and stress intensity parameters. The crack growth results above K//I//S//C//C could not be described by simple linear summation hypothesis, and this fact suggested the importance of the synergestic effect term in crack growth rate. This synergestic effect denoted as the dynamic SCC rate was strongly influenced by frequency and showed the maximum at a particular frequency.
