Abstract
Weld decay in the heat affected zone of austenitic stainless steel weldment can not be prevented perfectly only by existing techniques. In order to improve the intergranular corrosion resistance, a type 304 austenitic stainless steel was strained, heat-treated and then sensitized, varying the parameters (strain, temperature, time, etc.). The thermomechanically treated specimen showed an excellent intergranular corrosion resistance compared with the initial base material. The results suggest that the thermomechanical treatment can introduce low energy segments in the grain boundary network by annealing twins and can arrest the percolation of intergranular corrosion from the surface.
