Thermal fatigue crack growth in austenitic stainless steels

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review

Abstract

The effects of microstructural parameters on thermal fatigue crack initiation and short crack growth in austenitic stainless steels are studied. AISI 304, 316 and 321 type stainless steels were thermally fatigued in the temperature range of 20-300 degreesC. Such thermal fluctuations are typical of fatigue cracking, e.g., in nuclear power plant pipings. Development of thermal fatigue damage was monitored by replica assisted optical and SE-microscopy. Crack growth rate was estimated from striation spacing measurements. Actual thermal strains were measured directly from sample surface. Residual stresses caused by thermal cycling were measured by X-ray diffraction.
