Effect of Ti and Nb Contents on Microstructure and Mechanical Properties of HfZrVTaMoWTi_xNb_y Refractory High‐Entropy Alloys

Refractory high‐entropy alloys (RHEAs) with excellent high‐temperature performance are attractive for high‐temperature structural applications. However, many RHEAs suffer from high density and poor room temperature (RT) malleability. Herein, the effects of Ti and Nb contents on the phase equilibrium and mechanical properties of HfZrVTaMoWTi x Nb y RHEAs are studied to achieve unique balanced properties in a wide temperature range. With the...
