Characterization of Creep Fatigue Cracking in Type 304 Stainless Steel
Abstract
The behaviour of initiation and growth of small cracks in high-temperature push-pull low-cycle fatigue (LCF) was investigated on a Type 304 stainless steel. The characterization of cracking was done both on the basis of the precise observation on the surface of as well as inside the specimens which were subjected to a wide range of isothermal loading conditions, and on the basis of the numerical simulation for initiation and growth of small cracks. Similar fundamental properties must be found in thermal fatigue and in other kinds of polycrystalline steels and alloys.
