Microstructure-property Interrelationships in Metastable Beta Titanium Alloys with Refined Distributions of the Alpha Phase: Yufeng Zheng1; Gopal Viswanathan1; Rajarshi Banerjee2; Hamish Fraser1; 1The Ohio State University; 2University of North Texas
    In the recent past, there has been much interest in the development of super-refined distributions of the alpha phase in a beta matrix in metastable beta titanium alloys. This paper will describe the metallurgical factors that influence the heterogeneous nucleation of the alpha phase, in these alloys, which results in these refined distributions. These factors involve instabilities (soft phonon modes) in the beta phase, and these have been directly observed using high resolution electron microscopy. The interest in these super-refined distributions of the alpha phase involves the anticipated new balances of properties that may result. The second part of this presentation will describe the interrelationships between microstructure and mechanical properties (tensile deformation), with an emphasis on the development of an understanding of the mechanisms of deformation, in these metastable beta titanium alloys. This research involves deformation of the hcp alpha phase, in line with the work of Prof. K.L. Murty!
