a stabilizing element and a titanium alloy

Preferential dissolution in the α-phase, so that the isotropic isocrystalline transition temperature increases and expand the α-phase region of the elements for the a-stabilizing elements, replacement elements, aluminum and interstitial elements such as oxygen, nitrogen and carbon. Aluminum is the main alloying element of titanium alloy, which has obvious effects on increasing the strength of the alloy, improving the high-temperature performance and reducing the density.

Titanium alloy is a phase solid solution composed of single-phase alloys, density is small, whether at general temperature or at higher temperatures of practical applications, are a-phase, organizational stability, wear resistance is higher than pure titanium, oxidation resistance. At a temperature of 500~600℃, it still maintains its strength and creep resistance, can be strengthened by heat treatment, has good thermal strength and thermal stability, good welding performance, good room temperature, ultra-low temperature and high temperature performance.
