Abstract: The phase transformations in Ti-10V-2Fe-3AI alloy during aging have been studied by means of X-ray diffraction and TEM techniques.The morphology and distribution of precipi- tated phases were examined.The lattice parameters of α and β phases as a function of the ag- ing time is obtained,the hardness variation of the specimens related to the aging temperature and time has been given as well.

Key words: Ti alloy, phase transformations
