Abstract
The effect of heat treatment on the mechanical properties (including fracture toughness) of the titanium alloy Ti-6Al-6V-2Sn has been investigated. Based upon a preliminary hardness survey of solution temperatures from 1300 to 1800°F, solution treatment temperatures of 1400, 1550, and 1700°F were selected for further aging heat treatments ranging from 700 to 1100°F for times up to 32 h. X-ray and electron microscopic observations and elastic modulus determinations were employed and correlated with the mechanical property data. A detailed discussion of the results and observations is contained in this paper.
