Abstract: The grain coarsening temperature (T (c)) is quite low in a ferrite/pearlite (F/P) banded steel as compared with a non-banded steel. Here it is shown that the low T (c) in the F/P banded steel can be increased significantly by applying cold deformation prior to austenitizing. The kinetics of abnormal grain coarsening above T (c) is also largely retarded by cold deformation. These observations should be attributed to the uniform distribution of fine AlN precipitates caused by cold deformation.
