摘　　要：借助差示扫描量热仪(DSC)与金相显微分析,对Cr5钢过烧临界温度进行了试验。用Thermo-calc软件模拟了各合金元素对于过烧温度的影响,并对计算结果进行线性回归分析。结果表明,在Cr5钢的成分范围内其合金元素含量与过烧温度基本为单调递减的关系,其中对于过烧温度起主要影响作用的是碳。The critical burning temperature of Cr5 steel was experimented and discussed by DSC method and metallographic analysis.With the Thermo-calc software, the effects of various alloying elements on burning temperature were simulated, and linear regression analysis was performed for the calculative results.The results show that the monotonic decreasing relationship exists between the content of alloying elements and burnt temperature in the scope of the composition of Cr5 steel, and carbon has a major impact on the burning temperature.
