Theory of Titanium Alloys for High Temperature Strength.

Abstract

Measurements of electronic properties including electronic specific hear coefficient, magnetic susceptibility, Hall coefficient, and electrical resistivity were made on binary and ternary titanium-based alloys with nontransition elements X = Al, Sn, and Ga. The results form the basis for a discussion concerning the electronic bonding mechanisms and their interrelationship with the mechanical properties. Both dilute alloys stabilized in the alpha (hcp) phase, and intermetallic compounds of the Ti3-X-type (long-range order alpha sub 2 (D0 sub r 19) structure) are considered. In addition, aging experiments on Ti-Mo alloys (our prototype for the beta (bcc)-isomorphous systems) have been carried out, in order to study the effect on electronic properties, of the formation and growth of the omega phase precipitate in the retained beta matrix.
