The effect of initial microstructure on the recrystallization behaviour of low carbon (LC) steel was investigated. Steel strip (0.05 wt.% C) of 2-mm thickness was heat treated to produce an acicular ferrite (AF) microstructure from coarse austenite. The AF material and a strip-cast (SC) material of similar chemistry produced by twin roll casting were cold rolled to 50%, 70% and 90% reduction, and annealed for various times in the temperature range 580–680 °C. The evolution of microstructure during recrystallization was studied by optical microscopy and electron backscatter diffraction (EBSD) in the SEM. The initial microstructure was found to have a substantial influence on the recrystallization behaviour. AF recrystallized at a substantially faster rate than SC due to a higher level of solute Mn causing substantial solute drag effects.
