摘　　要：以低碳贝氏体钢为研究对象,讨论了回火参数对材料硬度的影响,基于回火P参数理论建立了钢的回火性能预测模型,绘制了回火参数转换算图。硬度误差分析结果显示,误差在15%以内,此模型可以用于回火工艺参数的优化和回火性能的预测。Taking low-carbon banitic steel as the research subject,the influence of tempering parameters on the hardness of low-carbon banitic steel were discussed here.The mechanical prediction mode was established and the nomograph of tempering parameters was plotted based on P parameter.Error analysis shows that the error of predicted mode was within 15%which can be used for the mechanical predictions and tempering parameters optimization.
