Abstract
The invention discloses a high-temperature high-strength titanium-aluminum alloy. The high-temperature high-strength titanium-aluminum alloy comprises the following main components in percentage by mass: 46.0%-49.0% of Ti, 42.0%-45.0% of Al and 8.0%-9.5% of Nb as well as 0.2%-1.5% of secondary components which include at least one of C, B, Si, W, Mn, Mo, Cr and V and at least one of Y, Ce, Tb and Gd. According to the manner, the temperature, strength, hardness, stability, ductility, comprehensive toughness and the like of the titanium-aluminum alloy can be improved.
Description
Technical field
The present invention relates to metal material field, particularly relate to a kind of high strength at high temperature titanium aluminum alloy.
Background technology
Titanium aluminum alloy enjoys attention owing to excellent specific properties such as its low density, high ratio are strong, better oxidation-resistance.Yet the use temperature scope of conventional high temperature titanium aluminum alloy and can't satisfy use temperature more than 350 ℃ about 300-350 ℃.
Along with the progress of science, find that Nb can significantly significantly improve the oxidation-resistance of titanium aluminum alloy, and Nb has very high solubleness in titanium aluminum alloy, thereby titanium aluminium niobium alloy has obtained fast development.In the present titanium aluminium niobium alloy, content of niobium is all more than 9.5%, the alloying of the titanium aluminum alloy that too high content of niobium has limited, and its intensity and toughness are not ideal enough, affect its processing characteristics.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provide a kind of high strength at high temperature titanium aluminum alloy, can improve heat resistance, intensity, hardness, stability, ductility and the comprehensive toughness and tenacity etc. of titanium aluminum alloy.
