This study describes development of the
-factor method proposed earlier. The development is attempted by incorporating the absorption correction term into the equation relating the mass thickness to the characteristic X-ray intensity. It is shown that the advanced form of the
-factor method reduces restriction encountered by the earlier form and thus enhances applicability of the
-factor method. The advanced form is applied to the Ni-Al binary system and the Ti-Al-Cr ternary system. This application demonstrates the validity of the advanced form of the
-factor method. The relation between the factor and the
factor is discussed and an advantage of using the
-factor method is summarized.
