Quantitative Analysis on the Heat of Mixing of Liquid Alloys by Employing New Parameters

抄録

The present study was carried out in order to find out a rule controlling the heat of mixing of liquid alloys.
The bonding-parameter B of elements was evaluated based on the rigid rule on alloying. Values of the heat of mixing of total 138 alloy systems were regulated with success by values of the parameter. The relations between values of ΔH_0.5^M and absolute values of ΔB were essentially divided into the two kinds of parabolic and linear forms. It was thus made clear theoretically that the parameter B had the covalent and metallic characters.
