Solidification simulation of Al-Mg-Er alloys using CALPHAD method

摘要：

With CALPHAD(calculation of phase diagrams) method,the solidification paths of several Al-rich Al-Mg-Er alloys were calculated with Scheil—Gulliver model in the Thermo-calc software.And the amounts of several phases formed during solidification were also calculated.Synchronously,the heat-treatment temperatures of the same alloys were predicted by thermodynamic calculation.The calculated results show that by adding 0.4％Er (mass fraction),the strength effect of Er in Al-Mg alloy is better.This result is in agreement with the experimental investigations.
