摘要

研究了热循环和热输入对254SMo超级奥氏体不锈钢模拟热影响区的组织、晶粒尺寸、析出相和腐蚀性能的影响。结果表明:随着热循环和热输入量的增加，热影响区微观组织晶粒逐渐长大，抗点蚀性能不断降低，抗晶间腐蚀性能先降低后升高;在多次热循环和高热输入时，在热影响区出现析出相。

Multiple welding simulated microstructure and corrosion resistance of super austenitic stainless steel 254SMo welding heat affected zone

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.
