摘要：

High Zr-containing beta-type Ti-based alloys were designed using electronic parameters to investigate experimentally the effect of beta-phase stability on their elastic and plastic properties. Texture structures formed by cold rolling or recrystallization were related closely to the beta-phase stability and hence affected the mechanical properties. In tensile tests, as the beta-phase stability decreased, non-linearity in the elastic zone was enhanced and the work hardening tended to be diminished. Also, it was found that the lower beta-phase stability led to the weaker anisotropy of plastic properties, but to the stronger anisotropy of elastic properties. (c) 2007 Elsevier B.V.
