AND APPLYING THE JUSTIFICATION ISOTHERMAL SYSTEM IN TEACHING CHEMISTRY

For the complete definition of the properties of the ternary Bi–Cu–In system,there were performed the investigation of micro
structures, hardness by Brinel alloys. In the range of this ternary system, numerous alloys were tested for three vertical
sections, with molar ratio Sb: Cu= 1, Cu:In= 1, Sb:In=.1. By application of CALPHAD method, and software package PANDAT
8.1, there were calculated the isothermal cross section at 250C and 400C.
