Abstract
The invention relates to an ultrahigh-strength titaniumalloy and a preparation method thereof, and aims to solve the problem that the existing high-strength titaniumalloy can not have high strength and high ductility simultaneously. The ultrahigh-strength titaniumalloy comprises Al, Mo, V, Cr, Sn, Fe and the balance of Ti and inevitable impurities in certain percentage by weight. The preparation method comprises the following steps: 1, weighing all the components; 2, preparing a monoblock electrode; 3, preparing a consumable electrode; 4, preparing a cast ingot; 5, preparing a forging blank; and 6, performing upsetting and finish-forging to obtain the ultrahigh-strength titanium alloy. According to the invention, after the ultrahigh-strength titanium alloy is subjected to solid solution and aging, the strength and ductility can be as follows: the tensile strength is up to 1496 MPa, the elongation percentage is 14.5%, and the percentage reduction in area is 20.77%. The invention can be used for preparation of the ultrahigh-strength titanium alloy.
Description
technical field [0001] The invention relates to an ultra-high-strength titanium alloy and a preparation method thereof. Background technique [0002] High-strength titanium alloy refers to a titanium alloy with room temperature strength greater than 1100MPa after heat treatment. It not only has high strength, but also has good plasticity, toughness, and good corrosion resistance. It is mainly used to replace high-strength steel as aerospace vehicles. Structural materials, as well as spring materials, have become one of the main research directions of titanium alloys in various countries, especially the United States and Russia developed earlier in this regard. In recent years, the application proportion of titanium alloys in the aerospace field has gradually increased, and high-strength titanium alloys have also been developed and applied rapidly. For example, Ti-1023 high-strength titanium alloys have been used successively on 737, 747 and 757 of Boeing Company of the Unite...
