| Abstract Scope |
High-fidelity microstructure evolution and strength prediction models are valuable to industry for the design of robust manufacturing processes and assurance of consistent outcomes in terms of meeting product requirements. In recent years, several commercial software packages (TC-PRISMA, PanPrecipitation, JMatPro, etc.) have become available to industrial users. TC-PRISMA has been licensed by Haynes International. A validation study on two commercial Ni-base superalloys, HAYNES® 282® alloy and HAYNES® 233® alloy, was conducted. Specifically, the evolution of the mean gamma-prime size was simulated during iso-thermal aging out to several thousand hours and compared to measured values thereof. Furthermore, room temperature tensile properties were measured in the same aged conditions, correlated to the mean gamma-prime size, and compared to strength prediction models tuned for Ni-base superalloys. Critical material parameter inputs and the current level of predictive capability are discussed, along with suggestions for further improvements of these computational tools from a user perspective. |
