Abstract (en)
[origin: EP3896183A1] The invention relates to a lightweight high-entropy alloy with high strength and high plasticity and a preparation method thereof, belonging to the fields of metal materials and preparation thereof. The high-entropy alloy is mainly composed of Ti, Zr, V, Nb and M, wherein M is one or more of Al, Hf, Cr, Fe, Mg, Be, Li, Mo, Co, Ni, Si, B, O and N. By regulating contents of all the elements, the high-entropy alloy has low density, high strength and high plasticity so as to have a huge application potential in the field of engineering. Moreover, the preparation method of the high-entropy alloy is easy to operate as well as safe and reliable, the adopted raw materials are nontoxic and harmless, and the high-entropy alloy is economical and practical.
