| Description |
The present study demonstrates the role of hot rolling and quench temperature in determining the mechanical properties of low alloy steel processed through quenching and nonisothermal partitioning (Q&P) route. The results indicate that the abrasive wear resistance does not show any significant variation with quench temperature. However, a reduction in tensile strength and an increase in charpy impact toughness and elongation is observed with increasing quench temperature. Interestingly, the retained austenite shows high thermal stability at sub-zero temperature. Furthermore, during deformation through the wear process, the retained austenite experiences the TRIP effect that leads to improvement in wear resistance. The incorporation of hot rolling prior to Q&P led to a significant improvement in strength, energy absorption capability and wear resistance due to a considerable refinement of the microstructural constituents.
