This application discloses an ultra-high strength, lightweight Al-Ti-V-Cr medium-entropy
alloy in the field of medium-entropy
alloy materials technology. The
alloy comprises, by
mass percentage: Al: 24–28%; Ti: 45–50%; V: 10–14%; Cr: 10–14%; and the total content of
impurity elements is ≤0.01%. This technical solution obtains a medium-entropy alloy by mixing the four elements in a certain proportion, giving it characteristics such as ultra-high strength,
low density, high
temperature resistance, and excellent hot workability.
