Texture and microstructure development in a cold-rolled duplex stainless steel annealed at 800 °C

A cast of austenitic-ferritic duplex stainless steel was rolled 85% and then annealed at 800 °C to study the microstructural and texture changes in the material caused by these mechanical and thermal treatments. The austenite in the duplex alloy behaves as typical low SFE materials when rolled as well as annealed but larger spreads in orientation were observed, compared with rolled and annealed brass. The cold-rolled ferrite mainly consists of long microbands and has texture similar to cold-rolled carbon steel. Upon annealing, the ferrite undergoes recovery only and the rolling texture is thus retained.link_to_subscribed_fulltex
