High-Pressure Torsion: A Path to Refractory High-Entropy Alloys from Elemental Powders
MetalsFor the first time, the refractory high-entropy alloys with equiatomic compositions, HfNbTaTiZr and HfNbTiZr, were synthesized directly from a blend of elemental powders through ten revolutions of high-pressure torsion (HPT) at room temperature.
