摘要
The effect of heat treatment on the performances of multi-element low alloy wear-resistant steel (MLAWS), which is used to make the rolling mill torii liner, was investigated. The results show that the hardness and tensile strength increase as the quenching temperature is increased from 840 to 900 degrees C. However, the hardness decreases rapidly as the quenching temperature is increased beyond 900 degrees C, while the temperature has little influence on the tensile strength when it exceeds 900 degrees C. No clear influence on the impact toughness has been observed unless the quenching temperature is beyond 920 degrees C. As the tempering temperature exceeds 300 degrees C, tiny epsilon carbides separate out from martensite and bainite complex structures and cause the carbon content in the complex structures to decrease. This results in the toughness to increase significantly. The best wear resistance can be obtained by tempering at 350 degrees C. The optimum heat treatment of MLAWS comprises quenching at 900-920 degrees C and tempering at 350-370 degrees C. (c) 2005 Elsevier B.V. All rights reserved.
