then normalized hot rolled plate is cold rolled to 0.5 mm sheet by 4 roll reversing mill with 6 passes. Analysis results show that at surface region of hot rolled plate there are mainly random distributed larger equiaxial grains

the center area consists of fine equiaxial grains and lath shape grains and the strong rotating cube texture {001}〈110〉components occur in center area； After cold rolling

the strong a and y textures occur at surface region and the hot rolled  {001}〈110〉rotating cube textures are retained in cold rolled sheet.
