Abstract

Based on analysis of experimental data obtained by continuous observations using high temperature microscope during the creep test without interruption in vacuum a parametric equation of high temperature creep crack growth rate was given for 304 stainless steel. It is the thermal activation type. In this paper, high temperature crack growth rate at creep-fatigue interactions and fatigue are studied on line of this consideration, and thus, the comparison has been made between them with special reference to hold time effects. From these results the authors suggest that so-called frequency effect on this behavior consists of the loading rate and the hold time effect.
