The present invention relates to a method for producing a molybdenum alloy target, and solves the problem of low density and coarser grains of the molybdenum alloy targets in the prior art. The present invention comprises subjecting a mixed powder with a mass ratio depending upon the formula composition of a molybdenum alloy to a pre-press forming process to obtain a preformed molybdenum alloy target blank; placing the preformed molybdenum alloy target blank in a capsule and subjecting the capsule to processes of preheating for degassing and vacuum seal welding; subjecting the target blank to a hot isostatic pressing process to obtain a densified molybdenum alloy prefabricated target; removing the capsule; and subjecting the molybdenum alloy prefabricated target with the capsule removed to a temperature-rising and pressure-decreasing process, followed by finish machining to obtain a molybdenum alloy target.
