Enhanced Strength of a Mechanical Alloyed NbMoTaWVTi Refractory High Entropy Alloy. [PDF]

Materials (Basel), 2018
A NbMoTaWVTi refractory high entropy alloy (HEA) has been successfully synthesized by mechanical alloying (MA) and spark plasma sintering (SPS). The microstructure and mechanical properties of this alloy are investigated. It is observed that only two types of body-centered cubic (BCC) solid solutions are formed in the powders after ball milling for 40 ...
