Phase Stability and Solution Strengthening in Titanium Alloys.
Abstract
The program had to do with effects resulting from the addition of transition elements to titanium; while subsequent phases involved alloying with 'B-metals', or nontransition metals and the so-called interstitial elements. Alloying of titanium with transition metals and B-metals leads to two distinctly different classes of behavior. The alloying of titanium with a transition element results, to a first approximation, in the creation of a 'new' transition metal with an increased electron/atom ratio. The principal effect of the alloying of titanium (Ti) with another transition element (T2) is the increasing tendency for the room-temperature-stable quenched crystal structure to be bcc as the solute concentration is increased. The omega-phase is a precipitate which tends to be embrittling. Conclusions regarding the physical properties of an omega-phase alloy structure were based on a detailed analysis of the magnetic and superconductive properties of an aged-to-'metastable-equilibrium' Ti-Mo (10 at .%) alloy. The authors also conducted investigations of the Ti-Nb, Ti-Fe, Ti-Mn, Ti-V and Ti-V-Al alloy systems.
