Strength and stability is the principal element for influenceing high-temperature titanium alloy development.Many high-temperature titanium alloys by increase Al, Sn, Zr content can effectively improve the intensity of alloy, but rear heat endurance has different degrees of decline by long-term use.It is former Because being that more Al and Sn are added in alloy, it can cause to separate out substantial amounts of Ti3X (X=Al, Sn) brittlement phase, make alloy thermostabilization Property decline.Heat endurance characterizes the ability that material keeps plasticity and toughness under high temperature long duration of action, is high-temperature titanium alloy An important mechanical performance index.For ensureing that the high temperature long-term use reliability of high-temperature titanium alloy part has important meaning Justice.Therefore, the temperature in use of high-temperature titanium alloy is further improved, and make its combination property obtain matched well to turn into the weight of research Point.
The content of the invention
It is an object of the invention to provide a kind of high-temperature titanium alloy and preparation method thereof, solves existing high-temperature titanium alloy intensity Not enough, the problem of heat endurance difference.
The technical solution adopted in the present invention is a kind of high-temperature titanium alloy and preparation method thereof, specifically according to following steps Implement：
Step 1, according to mass percent Zr：4.5%-5.5%, Al：7%-9%, Sn：1%-1.5%, Si：0.5%- 0.6%, Nb：1%-1.5%, Ni：2%-3%, V：0.5%-0.8%, surplus are that Ti weighs each component；
Step 2, the raw material weighed is put into consumable vacuum arc furnace ignition, is evacuated to 5 × 10-3More than Pa, Ran Houchong Enter high-purity argon gas to 1.01 × 105Pa, be then smelted into high temperature alloy ingot at 3100 DEG C -3300 DEG C；
Step 3, high temperature alloy ingot obtained above is put into vacuum heat treatment furnace be heat-treated, in vacuum 5 ×10-3Pa-6×10-3Pa, after being incubated 12-24 hours at 950 DEG C -1000 DEG C of heat treatment temperature, furnace cooling, that is, obtain high temperature Titanium alloy.
The features of the present invention also resides in：
Ti in raw material is pure titanium；
Al in raw material is fine aluminium；
Ni in raw material is pure nickel.
The invention has the advantages that by improving the ratio of aluminium in the feed, the high-temperature mechanics of high-temperature titanium alloy are improved Performance.Metallic nickel has good plasticity and corrosion resistance, and by adding pure nickel in the feed, the heat for improving high-temperature titanium alloy is steady It is qualitative.
