Quick Summary

A beta alloy refers to a metallic alloy where the beta phase is a significant component. In metallurgy, metals can exist in different crystal structures at varying temperatures. For instance, titanium and iron exhibit allotropy, meaning they can transform between crystal structures like alpha (\u03b1) and beta (\u03b2) as temperature changes.1

The beta phase in metals like titanium is a body-centered cubic (bcc) structure, which is stable at higher temperatures. Alloying elements can influence the stability of these phases, with some stabilizing the beta phase at lower temperatures. Beta alloys are particularly useful when high tensile strengths are required.2

Alpha and beta phases
pure, alpha, alpha-beta, and beta. Each class has distinctive characteristics. Pure titanium, although very ductile, has low strength and is therefore used when strength is not critical and corrosion resistance is desired. The alpha alloys are weldable and have good elevated-temperature strengths. The alpha-beta alloys are widely used because…
