| Abstract: | In this paper, a set of new methods have been proposed for calculating activities of componentsfrom the phase diagram in a binary eutectic system under different given conditions. As an example,activity calculation was carried out for binary system Al-Sn, and the obtained result is in excellentagreement with the experimental one. Therefore, the proposed methods can be utilized accurately anduniversally. |
