| Abstract Scope |
Many Ni-based superalloys are known to be susceptible to a wide range of cracking mechanisms, which occur during solidification as well as in the solid state. This cracking susceptibility is responsible for many Ni-based alloys being considered “unweldable” or “unprintable.” In this presentation, we show how we used analytical solidification models to design and introduce nucleation sites during solidification that modify the as-solidified microstructure and eliminate solidification cracking in both solid solution and precipitation hardened Ni-based alloys. We discuss how our method of using analytical solidification models can be applied to solve cracking in other materials systems or additive manufacturing processes. |
