Abstract
The study concerns cost-effective realization of Thermomechanical controlled processing (TMCP) in a forging process. The goal of the study was to produce mechanical properties of the steel in as-forged direct-cooled condition equivalent to those of quenched-tempered structural steel with simultaneous energy-savings benefits. The results of satisfactory implementation into hammer forging of a complex-geometry made of microalloyed medium-carbon steel 38MnVS6 in industrial conditions are presented. The use of finite element analysis for estimation of proper run of cooling curves and full-scale simulation for reproducible hot deformation and cooling conditions resulted in producing Rm over 1 120 MPa with elongation reaching 20 %.
