摘要
通过理论分析,本文证明了Fe-Cr-Si三元系中组元Si及Cr在一定浓度范围内具有正规溶液的性质。利用此性质,根据Si、Cr的相对偏摩尔混合焓ΔH_si^M、ΔH_Cr^M计算出Si、Cr的活度a_Si、a_Cr。
It is verified that in a certain range of concentration the elements Si, Cr possess regular solution properties in the ternary system Fe-Cr-Si. According to this character and by use of the relative partial molar enthalpy data △HMSi and △HCrM the activities of Si and Cr at the temperature of 1600℃ are calculated.
