Abstract

CALPHAD database coupling non-equilibrium multi-phase field method is applied to study hot tearing analysis for a practical engineering nickel alloy in the powder bed fusion process. It is confirmed that the probability of liquid film between grains varies with the cooling rate differences. Al solute segregation is also confirmed to be vary with the probability of liquid film
