Mechanical, Metallurgical Characteristics and Corrosion Properties of Equal Channel Angular Pressing of Duplex Stainless Steel
Abstract:
Duplex Stainless Steel (DSS) is well known for their higher mechanical strength and better corrosion resistance. DSS is commonly used for marine construction, petrochemical and chemical industries. DSS (2205) is having equal amount of α and γ phases.The present study was conducted on12mm diameter rod of the UNS S32205 duplex stainless steel subjected to equal channel angular pressing (ECAP). The refinement of original grains was observed. Effect of microstructure change on the corrosion behavior of equal channel angular pressed (ECAP) UNS S32205 duplex stainless steel was investigated. After single pass ECAP process and study about the pitting corrosion resistance. The mechanical properties of UNS S3 2205 duplex stainless steelwere evaluated. The amount of ferrite after ECAP and before ECAP for the two different conditions was investigated. Also observed percentage of ferrite content reduces 3.32% after ECAP.
