Abstract
The application provides an energetic high-entropy alloy for a shroud, a preparation method and application thereof, and the high-entropy alloy contains, in atomic percentage, Ti: 25-60%; Zr: 10%-35%; Nb: 10%-35%; Ta: 0%-20%; Al: 1%-20%; and V: 1%-20%. The preparation method comprises the following steps: firstly, Ti element particles, Zr element particles, Ta element particles, Nb element particles, Al element particles and V element particles are proportioned according to atomic content proportioning; then, alloy smelting preparation is carried out in a vacuum environment; finally, the prepared alloy ingot is subjected to hot isostatic pressing treatment to obtain the high-entropy alloy. The alloy is of single-phase BCC structure, has high strength and good room-temperature tensile plasticity. Due to the design of active elements, the alloy has the characteristics of high activity and high sound speed, which makes the high-entropy alloy shroud have the effects of high penetration and large opening.
