摘要
The influence of deformation temperature,strain rate and alloying elements such as chromium,nickel,copper,on corrosion resistance of a 304 stainless steel after plastic deformation was investigated.The techniques employed were tensile test at room and elevated temperature,deep drawing tests at various strain rates,X-ray diffraction test and potentiodynamic and cyclic polarization,metallography by optical and scanning electron microscopy.Results showed that chromium,nickel and copper had a significant effect on corrosion resistance of steel after plastic deformation.It was observed that corrosion resistance after plastic deformation was a function of deformation temperature and alloying elements.
