摘要：
The effect of quenching temperature, tempering temperature and tempering time on hardness of 45CrMnSi steel was studied by orthogonal test. It was found that the order of significant factors for the hardness was quenching temperature > tempering temperature > tempering time. Based on the results of the range analysis, the optimum process parameters for the maximum hardness were that the quenching temperature was 900 degrees C, the tempering temperature was 150 degrees C, and the tempering time was 180 min. Under the optimum process conditions, the hardness reached to HRC52 with impact toughness of 15 J/cm(2). The hardness and toughness met the need of the comprehensive mechanical property and proper toughness of 45CrMnSi.
