摘要
从含化合物金属熔体的原子本性和分子本性(活度的负偏差、混合△G和△H显示最小值、过剩稳定性的突然升高、电阻率显示最大值和相图等)出发,提出了反映本熔体实际的原子和分子共存理论。根据此理论制定了不同金属熔体作用浓度(即实测的活度)的计算模型。计算结果与实际符合的事实证明共存理论恰当地反映了含化合物金属熔体的结构本质。
Based on the atomicity and molecularity(negative deviation of activities from Raoultian behavior, minimum ΔG and ΔH of mixing at certain composition, abrupt go up of excess stability as well as maximum resistivity at compound formation composition and phase diagrams) the coexistence theory of metallic melts structure involving compound formation has been suggested. According to this theory, calculating models of mass action concentrations for different molten alloys have been deduced. The fact that calculated Ni and Nj with these models are in good agreement with measured ai and aj confirms that the coexistence theory of mentioned melts appropriately reflects the structural reality of these melts.
