Precipitation hardening design for next generation of endurant Ni-base super alloys - Phenix

Purpose and goal

The project aims to address gaps in Ni-base superalloy design tools and develop setups for analyzing nano-scale precipitates. This feasibility study will evaluate experimental techniques to benchmark simulations and identify in situ measurement methods for precipitation kinetics, and assess the ICME framework´s ability to predict nanostructure evolution and properties while identifying development needs. Findings will support decisions for a future full-scale project in materials engineering.

Expected effects and result

The project will provide a comprehensive study on integrating simulations and experiments to examine nanostructure evolution and properties in two reference Ni-base superalloys, using simulations, LSI measurements, and lab tests. It will assess computational tools, identify gaps, and outline a plan for in situ LSI measurements. A workshop will showcase these tools to encourage industry adoption, and the project will conclude with a full-scale proposal and technical report based on the findings.

Planned approach and implementation

A literature review will first be conducted to understand relationship between nanoprecipitates, heat treatments, and material properties, which will guide to plan the experiments and simulations. The next step is to perform ex situ and lab experiments alongside simulations, followed by a comparison of the results. The findings will help identify gaps in computational design tools and inform the setup of in situ experiments. The final step is to outline a full-scale project based on this study.
