Magnesium-zirconium alloy and preparation method and application thereof

The invention relates to a magnesium-zirconium alloy and a preparation method and application thereof. The preparation method comprises the following steps that magnesium metal is heated to be molten, and magnesium metal liquid is obtained; metal zirconium is added into the metal magnesium liquid to form a mixed melt, stirring treatment is conducted for 10-15 min, then ultrasonic treatment is conducted on the mixed melt while stirring treatment is kept, and a preformed melt is obtained; and the preformed melt is formed, and the magnesium-zirconium alloy is obtained. According to the preparation method, stirring treatment and ultrasonic treatment are combined, dissolution of metal zirconium particles can be promoted, and the magnesium-zirconium alloy with the high zirconium content, fine particles and dispersed distribution is obtained. 本申请涉及一种镁锆合金及其制备方法和应用。该制备方法包括以下步骤：将金属镁加热至熔化，得到金属镁液；向金属镁液中加入金属锆形成混合熔体，进行搅拌处理10min～15min，随后在保持搅拌处理的同时对混合熔体进行超声处理，得到预成型熔体；使预成型熔体成型，得到镁锆合金。在上述制备方法中，将搅拌处理和超声处理相结合，能够促进金属锆颗粒的溶解，得到锆含量较
