Abstract Scope |
Refractory high entropy alloys (R-HEAs) have gained enormous attention owing to their extreme chemical stability and high strength at elevated temperatures. However, they exhibit very limited formability at room temperature (RT) and extremely high cost and density thereby limiting their applications. Here we present a refractory Ti58-x-yZr16V16Nb10AxMoy high entropy alloy (Ti-HEA) having a very low density of 5.6 g/cc and extreme tensile ductility of 50 % at RT along with the yield strength of 1.1 GPa. The excellent property profile of Ti-HEA is attributed to the smart design strategy adopted for Ti-HEA which involves combination of HEA, valence electron configuration theories thereby activating slip dominated deformation in single phase β-b.c.c. equiaxed micro-structure in-as-cast state. |
