Controlled austempering of hammer forgings aimed at pseudo normalized microstructure directly after deformation

[摘要] The study concerns cost-effective realization of controlled thermomechanical processing (CTMP) of medium-carbon and HSLA steel aimed at producing microstructure and properties equivalent to normalized condition directly after forging. The results of theoretical and physical modeling of hot forging with subsequent heat treating adopted for industrial realization in continuous manner were verified in semi-industrial conditions of a forge plant.
