摘要：
This paper studies the effects of thermal cycle and heat input on microstructure, grain size, precipitated phase and corrosion properties in the simulated heat-affected zone of super austenitic stainless steel 254SMo. The results show that the microstructure grains in the heat affected zone gradually grow up, the pitting corrosion resistance decreases continuously and intergranular corrosion resistance firstly decreases and then increases with the thermal cycle and heat input increase. The precipitated phase appears in the heat-affected zone at the multiple thermal cycles and high heat input. © 2020 Inderscience Enterprises Ltd.
