Abstract

The invention provides an ultrahigh temperature titanium alloy and a preparation method thereof. The ultrahigh temperature titanium alloy comprises 6.50-7.50wt% of Al, 3.0-5.0wt% of Sn, 3.0-6.0wt% of Zr, 1.5-3.0wt% of Mo, 1.5-2.5wt% of Nb, 0.7-2.0wt% of W, 0.8-2.0wt% of Nd, 0.2-0.5wt% of Si, and the balance of Ti and impurities. The ultrahigh temperature titanium alloy accords with orientation of the spaceflight titanium market, meets aircraft members, and is obtained by compounding eight alloy elements; a result of test of the mechanical properties of a rod made of the alloy shows that the alloy has good integral properties, and especially high temperature properties; additionally, the preparation method has the advantages of simplified process flow, reasonable arrangement, low cost and easy production; the alloy has market competitiveness; and optimized design reduces the process difficulty and makes the alloy have good expandability.

Description

technical field [0001] The invention relates to the technical field of titanium alloys, in particular to an ultra-high temperature titanium alloy and a preparation method thereof. Background technique [0002] At present, due to its high strength, good plasticity, toughness, and good corrosion resistance, titanium alloys are mainly used to replace high-strength steels as structural materials and spring materials in aerospace vehicles. It has become one of the main research directions of technologies in various countries One, especially the United States and Russia developed earlier in this respect. my country's titanium alloy has experienced more than half a century of development, and has become one of the world's largest titanium countries, but there is still a gap between the world's powerful countries, which is reflected in the specifications and performance of high-end titanium alloy products, especially in the quality of titanium alloys for special purposes. big gap. ...
