抄録

Change in the orientation of equiaxed grains and columnar grains during hot rolling was investigated for 16%Cr ferritic stainless steel with about 50% γ-phase from 1050 to 1160°C. In comparison between equiaxed grains and columnar grains 60 seconds after hot rolling, the peak angle of the orientation distribution of columnar grains was from 25 to 30 degrees, whereas that of equiaxed grains was from 40 to 45 degrees that was close to ideal random orientation distribution. In the equiaxed grains immediately after hot rolling, recrystallized grains around (111)//ND nonrecrystallized grains did not have particular orientation. On the other hand, recrystallized grains around (001)//ND non-recrystallized grains formed (001)//ND orientation. It was cleared that equiaxed grains did not have particular orientation in cast slab formed gradually (001)//ND orientation by repeated hot rolling.
