在分析已有的热力学数据基础上,建立了估算二元金属间化合物比热容的双参数模型.用此模型可以估算由简单金属形成的二元金属间化合物的比热容,涉及Fe、Si、Nb、Ti、Cu、Co和Mg等多个体系.估算了132个已知金属间化合物AlCa、AlCo、CrNi、FeTi、FeSi、FeNb和MoSi等的比热容,平均误差为2.74J.mol-1.K-1,标准差为3.84J.mol-1.K-1.用双参数模型估算的比热容精度高,其估算误差小于离子束缚模型.
Based on the analysis of existing thermodynamic data, a two-parameter model for estimating the specific heat capacity of binary intermetallic compounds was established, which can be used to estimate the specific heat capacity of binary metallic compounds formed from simple metals, including Fe, Si, Nb, Ti , Cu, Co and Mg, etc. The specific heat capacities of 132 known intermetallic compounds AlCa, AlCo, CrNi, FeTi, FeSi, FeNb and MoSi were estimated with an average error of 2.74J.mol-1.K-1 , And the standard deviation is 3.84J.mol-1.K-1.The specific heat capacity estimated by the two-parameter model is more accurate than the ion-bound model.
