Assessment of effects of aluminum solid solution decomposition on geometric structure of Al-Sn-Zn isobar phase diagram

Three-dimensional (3D) computer model of the Al-Sn-Zn isobaric phase diagram is presented. It shown that T-x-y consists 64 surfaces and 25 regions. Features Al-Zn binary system related to decomposition aluminum solid solution its influence on geometric structure liquidus solidus in ternary system, formed by this tin, are considered. Critical analysis published data was carried out errors visualization those fragments T-x diagram, which regions with participation new solutions, appeared after initial solution, discussed. To design 3D model, literary were used, assessment quality based isopleths isothermal sections from same primary sources.
