Abstract
A method of manufacturing investment casting from titanium alloys includes production of a mould, filling, gas-static compaction of castings. At first, alloy is poured into the mould, without filling a cavity of head, and prior to gas-static compaction sizes of shrinkage pores are determined, for example by X-ray method, and location of depressions after gas-static compaction is corrected. After this, at subsequent production of the moulds above the places of shrinkage pores compensating cavities are performed, which size is determined from dependences: h = 2a, S = 6b, I = 6c, where: h, S, I - height, width and length of the compensating cavities respectively; and a, b, c height, width and length of the shrinkage pores respectively, determined after filling metal into the mould without heads. The gas-static compaction of castings is performed together with the compensators.
