Abstract
This paper examined the effect of Si addition on the cracking resistance of Inconel 939 alloy after laser additive manufacturing (AM) process. With the help of CALculation of PHAse Diagrams (CALPHAD) software Thermo-Calc, the amounts of specific elements (C, B, and Zr) in liquid phase during solidification, cracking susceptibility coefficients (CSC) and cracking criterion based on |dT/dfs1/2| values (T: solidification temperature, fs: mass fraction of solid during solidification) were evaluated as the indicators for composition optimization. It was found that CSC together with |dT/dfs1/2| values provided a better prediction for cracking resistance. Graphical abstract: [Figure not available: see fulltext.].
