Simulation of MoNbTaW Refractory High Entropy Alloy (RHEA) Optimization for High Temperature and Strength Applications
Aircraft engine efficiency depends on the operating temperature, where current nickel-superalloys are limiting that temperature to 800°C to preserve mechanical strength. The refractory high entropy alloy (RHEA) MoNbTaW has the desired mechanical properties of the current conventional alloys but maintain those properties at much high temperatures, exceeding 1200°C. This project’s purpose is to find compositions of the RHEA that maintain the high temperature mechanical strength while minimizing the shortcomings of room temperature brittleness by optimizing short range order, diffusion anti-phase boundary energy, and lattice distortion.

Sponsored project | Spring 2024
Jonathan McGill’s FURI project is sponsored by the Ahmad Family Fulton Undergraduate Research Initiative Fund.
Jalal U. and Syeda F. Ahmad and their children — Jaheen N., Raisa N. and Nafisah N., all of whom attended the Fulton Schools — established a fund to give back and support undergraduate students in their pursuit of knowledge and the advancement of research. Their endowment, which funds a materials science, mechanical, biomedical or electrical engineering student, was created to help more students have the life-changing experience of conducting research through FURI.
