【摘要】 本文从X射线衍射强度测定了高速钢中MC碳化物相的德拜特征温度(θ_DE),并从理论上提出直接计算合金相的德拜特征温度(θ_DT)的模型θ_DT=sum from i=1 to n C_i（θ_D）_i式中n:合金相中的组元数,C_i:第i组元的原子百分含量,（θ_D）_i:第i组元的德拜特征温度。从实验上得出,本文提出的模型是合理的。更多还原

【Abstract】 The Debye characteristic temperature of MC carbide in high speed steel (θ_DE) has been determined from X-ray diffraction intensities and a theoretical model for calculating the Debye characteristic temperatture of an alloy phase(θ_DT) is proposed where n is component number in the alloy phase, C₁ the atom percent of the ith component, （θ_D）₁ the Debye characteristic temperature of the ith component. It is shown from the results that the model proposed in this paper is reasonable.更多还原
