Abstract

The invention discloses an intermediate alloy for preparation of titanium alloy and a preparation method thereof, relating to aluminum-molybdenum-tin (aluminum-molybdenum-tin-based) intermediate alloys for preparation of the titanium alloy and preparation methods thereof. The alloy is characterized by containing the following alloy compositions in percentage by weight: 20.0-25.0% of Mo, 20.0-25.0% of Cr, 10-15% of Sn, 10-15% of Zr and the balance of Al. According to the aluminum-molybdenum-tin-chromium-zirconium alloy disclosed by the invention, metallic compounds, which take molybdenum, tin, chromium, zirconium and the like as main ingredients, have the characteristics of good brittleness and easiness in fracture, and a titanium alloy production process is shortened and is easier in operation. According to the preparation method, oxides are taken as raw materials, so that the cost is low, the smelting process is stable, and the state of alloy forming is good; the alloying is uniform, and elemental metals are added to titanium sponge and aluminum beans in the form of intermediate alloy, so that the degree of segregation of the titanium alloy is lowered.

Description

technical field [0001] A master alloy used for preparing titanium alloys and a preparation method thereof, relating to an aluminum-molybdenum-tin (aluminum-molybdenum-tin-based) master alloy used for the preparation of titanium alloys and a preparation method thereof. Background technique [0002] Titanium alloys are widely used in military industry, aerospace industry and civil industry, and master alloys are important raw materials for the production of titanium alloys. At present, most titanium alloy master alloys use binary alloys and ternary alloys. In order to meet the performance requirements during use, several binary alloys or ternary alloys need to be added. process poses difficulties. There is a need for an intermediate alloy that can adjust the components of the multi-element alloy at the same time and is easy to operate. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of the above existing technologies, ...
