The Property And Usage Of Titanium Material

Titanium alloy is a structural metal, it refers to the titanium and other metals manufactured from the alloy metal, from the 1950s began to develop, and more prominent is the aerospace field of high-temperature titanium alloy and structural titanium alloy. By the 1970s, only to develop a number of corrosion-resistant titanium alloys were, after the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys further developed, The aerospace sector began to widely purchase titanium alloy materials.

Due to the superior performance of titanium alloys, which makes titanium alloys in the field of new materials with a wide range of application prospects. There are different types of titanium alloys, and the characteristics of titanium alloys are also different. The most characteristic is that it has low density, high specific strength, low thermal conductivity, high-temperature resistance, low-temperature resistance, corrosion resistance, etc. And two of the most important characteristics are high specific strength and good corrosion resistance.

These two outstanding characteristics determine that titanium alloys have a very wide range of uses in the sea, land, air, and outer space, specifically in aerospace, conventional weapons, naval and marine engineering, nuclear and thermal power generation, chemical and petrochemical, metallurgy, construction, transportation, sports equipment, and household goods. Artificial earth satellites, moon modules, manned spacecraft, and space shuttles also use titanium alloy plate welded parts.

The preparation of titanium alloy generally goes through three steps of heat treatment, cutting, de-oxidation, and pickling to manufacture the initially finished titanium alloy, while titanium alloy from melting to the final product generally requires three steps of titanium sponge preparation, titanium preparation, and titanium application. Titanium sponge and titanium preparation technology is complex and difficult to prepare, is the titanium manufacturing difficulties and key links, to a certain extent, titanium sponge and titanium materials directly determine the quality of finished titanium alloys. From the whole industry chain, the core barrier of titanium alloy does not only lie in the upstream resources and midstream smelting, but in the processing of titanium, high-end titanium R & D, and the manufacturing process is often concentrated in the hands of leading enterprises.

The current high-end titanium processing mainly uses vacuum white consumption arc melting technology (VAR). Vacuum white consumption arc melting technology simply means that in a vacuum or inert gas environment, the induction furnace production of self-consumption electrodes through controlled AC arc heating melting. This technology has very strict requirements for heat treatment technology, and cutting process. At present, only several countries, including China mastered the complete high-end titanium processing technology.
