Zusammenfassung:	The invention provides a manufacturing method for a molybdenum-niobium target blank. The manufacturing method comprises the steps that molybdenum and niobium mixed powder is provided; the cold isostatic pressing process is conducted on the molybdenum and niobium mixed powder, and thus a molybdenum and niobium powder blank material is formed; the molybdenum and niobium powder blank material is putinto a sheath, the sheath is vacuumized so as to be a vacuum sheath, then the hot isostatic pressing process is conducted on the molybdenum and niobium powder blank material, and thus a molybdenum-niobium alloy is formed; and the vacuum sheath is removed, and thus the molybdenum-niobium target blank is obtained. The cold isostatic pressing process is adopted firstly to pre-form the molybdenum andniobium mixed powder into the semi-dense molybdenum and niobium powder blank material, and therefore better densifying of the subsequent hot isostatic pressing process is facilitated; and then omni-directional gas pressure equ
