Abstract
The present disclosure provides a ZA4 alloy and a preparation method and use thereof, and relates to the technical field of pure zirconium materials. In the present disclosure, the ZA4 alloy includes the following components by mass fraction: 0.2% to 0.6% of Fe, 0.1% to 0.3% of O, 0.5% to 4% of Hf, and Zr as a balance. The Fe and O with a trace amount make a grain size of the ZA4 alloy significantly refined during smelting and cooling, and inhibit growth of a grains during thermal deformation and heat treatment. The Hf is a neutral element, and shows an obvious solid solution strengthening effect in an a phase. The ZA4 alloy obtained by strictly controlling a content of each element has higher strength and plasticity. The preparation method has simple operations and a low production cost, and is suitable for industrial production.
