Reheat cracking—A review of recent studies

Abstract

The paper summarises the most recent information on the topic of reheat cracking in low alloy constructional steels, ferritic creep resisting steels, nickel-base alloys and austenitic stainless steels. Attention is paid to reheat cracking in weld metal, underclad cracking, the mechanism of reheat cracking and test methods. From the literature review it appears that there is still a considerable research effort being spent on the topic of reheat cracking although the problem of reheat cracking in practice has largely been solved.
