Project

Hydrogen absorption and desorption in refractory metal high entropy alloys with body centred cubic structure (GA21-16218S)

High entropy alloys (HEAs) represent completely new concept in materials. HEAs are currently a hot topic in materials science due to their unique physical properties. This project focuses on the development of refractory metal H...
