Preparation method of zirconia reinforced molybdenum alloy bar

The invention belongs to the technical field of nonferrous alloy materials and particularly relates to a preparation method of a zirconia reinforced molybdenum alloy bar. The preparation method of thezirconia reinforced molybdenum alloy bar comprises the following steps that ammonium molybdate and a zirconium nitrate solution are mixed, then ball milling and drying are performed, and then precursor powder is obtained after roasting; and the precursor powder is subjected to two-stage reduction in a reducing atmosphere, then compression moulding and sintering are performed, and the zirconia reinforced molybdenum alloy bar is obtained. The zirconia reinforced molybdenum alloy bar prepared through the preparation method has the characteristics of being uniform in texture, high in compactness,high in strength, good in plasticity and deep processing performance and the like. 本发明属于有色合金材料技术领域，具体涉及一种氧化锆增强钼合金棒材的制备方法。本发明的氧化锆增强钼合金棒材的制备方法包括以下步骤：将钼酸铵与硝酸锆溶液混合，然后球磨、干燥，之后焙烧得前驱体粉；将前驱体粉在还原气氛中进行二段还原，然后压制成型，烧结，即得。本发明的制备方法制得的氧化锆增强
