ESTIMATION OF STRUCTURAL VOLUME FRACTION OF PHASES AND RELATIONSHIP BETWEEN PHASE AMOUNTS IN MULTI-PHASE ALLOYS
多相合金组成相结构体积分数及相含量之间关系的测算

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.
