The heat treatment consists of intermittent heating cycles during the cooling stage to check the nucleation of fine γ′ in the material during the overaging. Using Rene 80 alloy as a model material, the effects of intermittent heating rate and duration were studied and optimised. Quantitative metallography was carried out to compare the microstructures produced by the proposed heat treatment with those produced by other conventional pre-weld heat treatments. Tensile tests and welding tests both showed that the proposed cyclic over-aging heat treatment is effective in improving the tensile ductility and weldability of Rene 80 alloy. © 2002 IoM Communications Ltd.||Source Title:||Materials Science and Technology||URI:||http://scholarbank.nus.edu.sg/handle/10635/58054||ISSN:||02670836||DOI:||10.1179/026708302225002038|
