摘      要：The influence of different heat treatment strategies on the microstructure and properties of 42SiCr steel was *** compare the benefit of innovative treatment methods with more conventional ones,several strategies based on a new quenching and partitioning (Q-P) process were designed together with several strategies using more traditional quenching and tempering *** combinations of mechanical properties were obtained with ultimate strengths in the range of 1818-2120 MPa and ductility between 10% and 24%.Resulting microstructures were martensitic with 0-12% of retained austenite and they were analyzed by laser scanning confocal microscopy,transmission electron microscopy and X-ray diffraction phase analysis.
