The objective of this work was to establish quantitative knowledge of the recovery and recrystallization processes occurring during the warm working of medium carbon and low alloy steels in the temperature range 600 C to 900 C with a view to facilitating prediction of microstructure and hence the properties of warm worked steels. Six steels were selected with compositions relevant to commercial warm forging, with carbon up to 0.48 %, manganese up to 1.34 %, chromium up to 0.96 %, molybdenum up to 0.2 % and vanadium up to 0.16 %. Microalloyed steels were also studied to assess their feasibility for warm working applications. Equations were developed for the kinetics of recovery, recrystallization, recrystallized grain size, recrystallization of niobium steel, tensile strength and phase fractions, and compared with experimental results.
