Abstract
The conventional route for tool steel manufacturing consumes large amounts of energy and time and results in a long process chain for the manufacture of products. Environmental consciousness is fuelling the development of an improved route with a shorter process chain and lower energy consumption that can replace the conventional one. An energy-efficient process route for manufacturing products with high quality was proposed based on recrystallization and partial melting (RAP) technology. To verify the feasibility of the RAP-based route, the effects of predeformation, partial melting, and post heat treatments on the microstructure characteristics and mechanical properties of cast Cr-V-Mo steel were studied experimentally. During the RAP process, plastic deformation, recrystallization, austenization, grain growth, and partial melting occurred. When the RAP processed specimen was quenched from 1050 oC after isothermal holding for 480 s and then tempered twice at 560 oC for 2h, microstructural evolution occurred in both former solid-phase and liquid-phase regions and caused a good combination of mechanical properties.
