Scientific Abstract
It is worked on novel hierarchical FeAl-based precipitate-strengthened alloys for high-temperature structural applications. Some of them show very unique hierarchical microstructure with L21 precipitates within B2 precipitates within a bcc matrix. This exciting group of materials resembles a promising low-cost alternative to Ni-superalloys and Ti-based alloys under specific conditions. A potential application for these alloys ultra-supercritical power plants with service temperatures ~760 °C, where their lower thermal expansion and their higher thermal conductivity are desirable. In this context, his research is primarily focused on the alloy development and optimization through microstructural and mechanical characterization.
