Thermodynamic database of multi-component Mg alloys and its application to solidification and heat treatment

摘要

An overview about one thermodynamic database of multi-component Mg alloys is given in this work.This thermodynamic database includes thermodynamic descriptions for 145 binary systems and 48 ternary systems in 23-component(Mg–Ag–Al–Ca–Ce–Cu–Fe–Gd–K–La–Li–Mn–Na–Nd–Ni–Pr–Si–Sn–Sr–Th–Y–Zn–Zr)system.First,the major computational and experimental tools to establish the thermodynamic database of Mg alloys are briefly described.Subsequently,among the investigated binary and ternary systems,representative binary and ternary systems are shown to demonstrate the major feature of the database.Finally,application of the thermodynamic database to solidification simulation and selection of heat treatment schedule is described.
