Abstract

The invention is intended for manufacturing a hollow fan blade for a gas-turbine engine. A joint-preventing coating is applied to the surface of sections of blanks not undergoing welding. The blanks are assembled into a stack and hermetically sealed along the edges. Cavities in the stack are evacuated and filled with an inert gas. A binder of the coating is removed by heating. Diffusion welding of the blanks is carried out. The blank is then arranged such that adjacent surfaces of blank linings and a filler are located in a horizontal plane, and adhesive bonds between the blanks and the coating are torn in sections where no joint had been formed, thereby producing a pressure in the cavities in the blank for elastic deformation of the blank linings and filler. The cavities in the blank are sequentially evacuated and filled with an inert gas in order to remove oxygen therefrom and, after evacuation, are subsequently hermetically sealed. A trough, a blade back and a blade body are formed from the blank by hot deformation. The blank is heated and a working medium is fed into the cavities, thereby producing a pressure for superplastic moulding to produce the hollow blade body and reinforcing ribs. The invention makes it possible to extend the technological possibilities for manufacturing a hollow fan blade.

The inventive alloy comprises the following components: 0.8÷2.2 mass % copper, 1.2÷2.6 mass % magnesium, 0.2÷0.6 mass % manganese, ≤0.2 5mass % iron, ≤0.20 mass % silicon, 5.0÷6.8 mass % zinc, ≤0.1 titanium, 0.08-1.7 mass % chromium, 0.01÷0.12 mass % zirconium, 0.0008÷0.005 mass % bore, (0.3-4.1)10 -5 mass % hydrogen, the rest being aluminium, wherein ≤0.25 mass % Ti+Zr+Cr and ≤8.6 mass % Cu+Mg+Zn. Said invention makes it possible to produce an alloy optimally combining strength and plasticity properties which provide wheel disks with required performance characteristics, reduce the mass thereof in combination with the high processabilty in die forging, in particular of irregular-shaped articles.

Abstract

The invention relates to non-ferrous metallurgy, in particular to producing modern titanium alloys exhibiting a high degree of genericity. The inventive titanium-based alloy comprises aluminium, vanadium, molybdenum, chromium, iron, zirconium, oxygen and nitrogen at the following component ratio: 4.0-6.0 mass % aluminium, 4.5-6.0 mass % molybdenum, 2.0-3.6 mass % chromium, 0.2-0.2 mass % iron, 0.1- less than 0.7 mass % zirconium, less than 0.2 mass % oxygen, less than 0.05 mass % nitrogen, the rest being titanium. Said invention makes it possible to develop a titanium alloy exhibiting required strength and plastic characteristics. The inventive alloy can be used for producing a large range of products, including large-sized pressed and forged products and a small cross-section semiproducts such as rods and plates whose thickens is equal to or less than 75 mm.
