Quick Summary

The term "beta transus" refers to the lowest temperature at which a 100% beta phase can exist in a titanium alloy. This temperature varies depending on the alloy's composition, ranging from 700°C to 1,050°C.1

Titanium is a lightweight, corrosion-resistant metal with a high strength-to-weight ratio. It exists in two crystalline forms: alpha (α) below 883°C and beta (β) above this temperature. Alloying elements can stabilize either the alpha or beta phase, influencing the metal's properties. Final mechanical and heat treatments are typically performed below the beta transus to achieve desired microstructures.1

Titanium alloys are categorized into four classes: commercially pure, alpha, alpha-beta, and beta, each with distinct characteristics for various applications, including aerospace and industrial uses.1
