A commercial 0.16% carbon, 1.5% Mn structural steel was heat treated in three different ways, cold rolled and then recrystallized at temperatures between 500-600 deg C. The heat treatments were: normalizing at 920 deg C, 30 min, air cool; Mn partitioning treatment at 715 deg C, 112 h, air cool; dual-phase treatment, i.e. a short intercritical anneal at 750 deg C followed by quenching in water. All treatments produced massive two-phase structures, in which the second constituent was pearlite, Mn enriched martensite, and non-partitioned martensite, respectively. It is shown that the recrystallization rates of the ferrite in the steel samples, deformed 54%, differ significantly. The recrystallization temperature of the normalized and or the dual-phase steel is considerably higher than that of the Mn-partitioned dual-phase steel. The results of the experiments are discussed and some explanations of the steels' different recrystallization behaviours are suggested. Photomicrographs, Graphs. 7 ref.--AA
