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.
