Radiation resistance of refractory high-entropy alloys

Response of refractory high-entropy alloys MoNbTaVW and HfNbTaTiZr to ultrafast radiation is modelled with the hybrid code XTANT-3, combining tight-binding molecular dynamics with the transport Monte Carlo and Boltzmann equation. A two-temperature state with elevated electronic temperature and a cold atomic lattice is studied.

Threshold displacement energies in refractory high-entropy alloys

Physical Review Materials
Refractory high-entropy alloys show promising resistance to irradiation, yet little is known about the fundamental nature of radiation-induced defect formation. Here, we simulate threshold displacement energies in equiatomic MoNbTaVW using an accurate machine-learned interatomic potential, covering the full angular space of crystal directions.

Heat storage in alloy transformations [PDF]

The theory of eutectic transformation was examined to find guidelines to the best material combinations to examine. The heats of transformation were measured calorimetrically, and the volume changes of expanding solid mixtures and homogeneous liquid ...

A bcc refractory high-entropy alloy: the ideal case of smooth plastic flow

Materials Research Letters
Single crystalline metals exhibit correlated dislocation dynamics, irrespective of lattice system. This collective evolution of dislocation structures is intermittent and scale-free, implying divergent length scales that play a critical role in failure ...
