Paper Title:
The Study on Microstructure and Properties of a New Metastable Beta Titanium Alloy after Aging Treatment
  Abstract

New metastable beta titanium alloy Ti-4Al-2.7V-12Mo-10Nb-1Zr-0.2Cr was carried out in the arc melting vacuum furnace. The microstructure and mechanical properties of a new metastable beta titanium alloy Ti-4Al-2.7V-12Mo-10Nb-1Zr-0.2Cr were compared at different aging temperature and time. The growth mechanism of α phase is analysed by comparing the morphology of the precipitated phase at different temperature. Test results indicate that titanium alloy Ti-4Al-2.7V-12Mo-10Nb-1Zr-0.2Cr has the best property through two-step aging treatment. The tensile strength of titanium alloy Ti-4Al-2.7V-12Mo-10Nb-1Zr-0.2Cr after final aging treatment achieves 1180MPa with 8% elongation trough tensile test. The strengthing mechanism was also discussed in this paper.
