[en] To date, Zn has not been used as an alloying addition in structural Ti alloys. The main obstacle has been the disparity between their melting and vaporization temperatures. A novel processing technique was developed to create a Ti-Zn compound. The equilibrium phases and microstructures were studied by electron microscopy and x-ray diffraction techniques. Results show the presence of pearlitic domains of α-Ti (hexagonal closed packed crystal structure) and Ti2Zn (body center tetragonal structure) in regions that have a near eutectoid composition. Solutionizing and water quenching results in the formation of martensite along with intermetallic laths, suggesting that the eutectoid transformation is active. - Highlights: • Novel synthesis method to produce a Ti-Zn alloy. • Active eutectoid transformation of the form βTi→αTi+Ti2Zn. • Quenching studies show formation of martensite at high Zn concentrations. • Solubility of Zn in α-Ti is much larger than in the equilibrium phase diagram. • Intermetallic Ti2Zn phase may display a nonstoichiometric composition.
