Abstract

The crystallographic orientation of cold-rolled 316L stainless steel is investigated during reversion of straininduced a-martensite to nano/ultrafine-grained austenite upon annealing at 750 C for different holding times; 1, 5, 15, and 30 min. The texture of nanoscale reverted austenite reveals a Brass ({110}Æ112æ) and a Goss ({110}Æ100æ) textures after annealing for 1 min. No new texture component is appeared through the completion of martensite to austenite reversion for 5 min, but the intensity of Brass and Goss textures are increased. Further annealing for 30 min results in a stronger texture with higher intensity for Brass compared to Goss.
