and grain orientation variation during the solution heat treatment process of the 304 stainless steel pipe were studied. It was found that after the solution heat treatment, the texture type clearly changed, and the texture strength was greatly increased. During the solution heat treatment process, grain boundaries migrated along the orientation available for grain growth, giving rise to abnormal......
