Abstract : An experiment designed to study the effect of several variables on the subcritical crack growth rate of a high-strength steel in a water environment was conducted. Double cantilever beam specimens of an AISI 4340 steel were employed to study crack extension rates. The environmental variables included temperature, pH of the liquid environment, electric charging and the combined effect of pH and electric charging. (Author)
