	1	Effect of welding parameters on the heat-affected zone of AISI409 ferritic stainless steel显示文摘One of the main problems during the welding of ferritic stainless steels is severe grain growth within the heat-affected zone(HAZ).In the present study,the microstructural characteristics of tungsten inert gas(TIG) welded AISI409 ferritic stainless steel were investigated by electron backscattered diffraction(EBSD),and the effects of welding parameters on the grain size,local misorientation,and low-angle grain boundaries were studied.A 3-D finite element model(FEM) was developed to predict the effects of welding parameters on the holding time of the HAZ above the critical temperature of grain growth.It is found that the base metal is not fully recrystallized.During the welding,complete recrystallization is followed by severe grain growth.A decrease in the number of low-angle grain boundaries is observed within the HAZ.FEM results show that the final state of residual strains is caused by competition between welding plastic strains and their release by recrystallization.Still,the decisive factor for grain growth is heat input.
