Title: Influence of Heat Treatment on Microstructure and Mechanical Properties of Multi-layer Stainless Steel Composite
Abstract: The microstructure and mechanical properties of 8-layered stainless steel composite prepared by accumulative rolling-bond(ARB) after annealing at 200 ℃~900 ℃ for(0.5~2) h were studied.The results show that,as the annealing temperature increasing,with a constant annealing time,the microstructure experiences an evolvement of recovery →recrystallization→grain growing,and the plasticity increases,but the tensile strength and microhardness decrease at the same time.Above 600℃,the change is remarkable.Meanwhile,with a constant temperature,as the annealing time increasing,both microstructure and mechanical properties change slightly.All the specimens exhibit no fracture or delamination when they are bent to 90°,and all the tensile test specimens are ductile fracture.For a better comprehensive mechanical property,annealing at 600℃ for 1 h is suggested.
