Here, we describe our recent efforts demonstrating direct current sintering parameters appropriate to mimic near-identical microstructure to optimize reduced activation ferritic martensitic “castable nanostructured alloy”. The fabrication process is presented, and through a combination of computational thermodynamics, multimodal characterization, and mechanical testing we confirm that sintering may be used to produce relevant castable nanostructured alloy (CNA). Our success in demonstrating the applicability of sintering to CNA fabrication opens the opportunity to fabricate functionally graded first wall tile structures or other complicated structures with demanding high-temperature performance, as example fusion high heat flux components.

EMREL awarded $420,000 NSF Award - Collaborative Research: Deformation Mechanisms in Microstructurally Tailored High-Strength Alloys Near the Ideal Limit
August 2023

A collaborative project involving Jason Trelewicz (EMREL) and the Advanced Casting Research Center at UC Irvine aims to push metals toward their ideal strength by studying how dislocations start and move in nanostructured aluminum and copper alloys. The team will combine atomistic modeling, multimodal structural characterization, and micromechanical testing to guide alloy development. The effort also introduces a Mechanics Interactive Teaming (MINT) learning module to broaden student training. The project will also introduce a new Mechanics Interactive Teaming (MINT) learning module to broaden student training.
