Explanation

It is called all titanium alloy, which is a kind of titanium alloy β The total content of stable elements exceeds the critical water solubility of P phase (a crystalline phase in titanium matrix). These alloy must contain 28% molybdenum equivalent or more β Stable elements. The structures of these alloy are stable and will not undergo phase transformation during any cooling or heating process, so they cannot be strengthened by heat treatment. Stability of one practical application β titanium alloy is Ti-33Mo. Its main characteristics include extremely high corrosion resistance, good process plasticity, which can prepare thin plates at room temperature, and is suitable for various weld processes. There is also a high-temperature and high-strength stability β titanium alloy is Ti-24V-10Cr. On the basis of making full use of solid solution strengthening, it has carried out dispersion strengthening by adding rare earth elements and combining with oxygen in the matrix. Although stable β titanium alloy has excellent properties, but it also has some disadvantages, such as high density and poor elastic modulus. More research work is still needed before it can be widely applied.
