| Abstract Scope |
Our understanding of solidification cracking in nickel-based alloys has been derived from experiments that vary a single alloy addition and assess its impact (e.g., Haynes 230 with/out Zr), or susceptibility models based on Scheil–Gulliver simulations. Although recent studies have compared the predictive performance of different susceptibility models for nickel alloys by correlating with Varestraint experiments, these studies have been conducted over a very narrow range of alloy chemistries. In this work, we calculate the susceptibility from CALPHAD simulations of 50 AWS compositions and use materials informatics and statistical models to explore how different elements affect the susceptibility predictions and experimental observations. The results of this work could inform engineers during root cause analysis of failed welds, help determine which microstructural interactions to consider when developing more predictive susceptibility models, or aid researchers in developing alloys for new joining or additive manufacturing applications. |
