Abstract:

This studies were carried out to clarify recrystallization behaviors of low carbon 18%Cr stainless steel and 20%Cr-80%Ni and 30%Cr-70%Ni alloys with the RD||< 110 > rolling texture.
The results are as follows:
Recrystallization of {001}< 110 > domains on the low carbon 18%Cr stainless steel was completed with the appearance of subgrains at the same time when {001}< 110 > domains recovered wholly, and did not show grain growth. Hence recrystallization grains were nucleated in situ for matrix. {111}< 110 > domains were recrystallized along the rolling direction to extremely large secondary recrystallization grains notwithstanding their late start. On the Cr-Ni alloys which did not show the ridging phenomenon notwithstanding their having the RD||< 110 > texture, the RD||< 110 > compornent tended to decrease after recrystallization. In alloys slow-cooled during heat treatment before cold rolling, the RD||< 110 > component diminished at smaller reduction than quenched ones.
