摘要
导出了多相合金组成相结构体积分数以及用成分的原子分数与质量分数求得的相含量之间的关系.结果表明,组成相结 构体积分数是由质量分数算得的相含量和相密度的函数,尽管用原子分数与用质量分数求得的合金相含量以及与该相的结构体积分 数可能在数值上相差甚小,但它们数值来源的物理量不同,其间有定量关系,并可在一定条件下反映出其各自的特征.
Formulae for the structural volume fraction of phases and the quantitative relationship between the phase amounts obtained respectively by calculations in atomic fraction and in mass fraction of elements are derived for multi-phase alloys. It is shown from the results that the structural volume fraction of phases is a function of their amount and density. Although the discrepancy between the structural volume fraction and the amount fraction of the phases investigated is minor, their data sources are different in physical sense and might show their individual characteristics in a certain condition.
