Effect of Cold Work Percent on Mechanical Properties of AISI 304L Stainless Steel
2009 (Persian)Conference paper, Abstract (Refereed)
This article investigates the effect of various degrees of plastic deformation introduced by cold rolling at zero temperature on the mechanical properties of AISI 304L stainless steel. microstructural and ferromagnetic studies were also conducted. The material was evaluated up to 90% reduction in thickness. For this purpose, magnetic measurements, optical metallography, hardness and Tensile test, were used. Results show that by increasing the amount of rolling strain, transformation of austenite to martensite generally increases. The regime of this increase depends on the amount of the plastic deformation and temperature. The tensile strength and hardness were found to increase with the increase of cold rolling percentage (%CR) up to 90%.The results indicate that the formation of strain-induced martensite evidently led to a significant strengthening of the steel.
