摘　　要：利用材料模拟软件JMatPro模拟了近百种不同合金成分的水轮机用材料在碳当量为0.48%的情况下的屈服强度和抗拉强度的变化情况。得到了在碳当量一定的情况下,不同的化学元素C、Mn、Mo、V、Cr、Si和微量元素B等对材料强度的影响规律,为水电产品锻件的生产制造提供了理论依据。By adopting the material simulation software JMat Pro,when the carbon equivalent is 0.48%,the changes of yield strength and tensile strength for nearly hundred kinds of material with different alloy content used for hydraulic turbine have been simulated.The influence rule of different chemical elements such as,C,Mn,Mo,V,Cr,Si and B on the strength of material under a certain carbon equivalent has been obtained,so as to provide the theoretical basis for manufacturing the forgings used for hydro power.
