... alloys are classified according to the amount of alpha and beta retained in their structures at room temperature. Classifications include commercially pure, alpha and near-alpha, alpha-beta, and metastable beta. The commercially pure and alpha alloys have essentially all-alpha microstructures. Beta...

.... The response of titanium and titanium alloys to heat treatment depends on the composition of the metal. The basic alpha, near-alpha, alpha-beta, or beta alloys have heat treatment responses attuned to the microstructure (phases and distribution) that can be produced in a given alloy. In simpler terms, heat...
