    Abstract:

    The properties of titanium alloys can be improved by cold deformation and aging heat. However, there are limited report on the performance transformation of titanium alloys under the combination of cold deformation and aging heat treatment. In this work, the influence of prior cold deformation and the subsequent aging heat treatment on the phase types, α precipitation behaviors and the tensile properties of TB9 titanium alloy were studied using the X-ray diffraction, optical microstructure, scanning electron microscope and uniaxial tensile. The results showed that longitudinal and cross section of the bars formed different type macro texture through produced different microstructure and affected the microhardness. TB9 titanium alloy consisted of α and β phases after aging heat treatment. With the increase of the cold deformation rate, the tensile strength was increased and the ductile was reduced. Due to the defects produced during the cold deformation process, the precipitation free zones were disappeared in cold deformation samples and the mixmum tensile strength reach 1800MPa with an elongation of 4%.
