Accelerated oxidation in ductile refractory high-entropy alloys

Intermetallics, 2018
Refractory high-entropy alloys (RHEAs) are promising candidates for new-generation high temperature materials, but they generally suffer from room temperature brittleness and unsatisfactory high-temperature oxidation resistance. There currently lack efforts to address to these two critical issues for RHEAs at the same time.

Structure and Properties of Refractory High-Entropy Alloys

2014
Many exciting properties such as high hardness, high strength, wear resistance and oxidation resistance are generally observed due to the distorted lattice and slow diffusion rate in high-entropy alloys (HEAs). In this study, HEAs based on refractory metals like Hf, Mo, Nb, Ta, Ti, W and Zr are studied with the goal to develop both ambient and high ...

Phase Transformations in Refractory High Entropy Alloys

High entropy alloys (HEAs) based on refractory elements have shown a great potential for high temperature structural applications. In particular, the ones containing Al, exhibits a microstructure similar to the γ-γ' in Ni-based superalloys. While these alloys exhibit impressive strengths at room temperature (RT) and at elevated temperatures, the ...
