【 摘 要 】

This paper presents the results on the influence of different thermo-mechanical processing (TMP) on themechanical properties and electrochemical behavior of newmetastable �?-alloy Ti�??20.6Nb�??13.6Zr�??0.5V (TNZV). TMP included hot working in below �?-transus, solution heat treatments at same temperature in different cooling rates in addition to aging. Depending upon the TMP conditions, a wide range of microstructures with varying spatial distributions and morphologies of equiaxed/elongated �?, �? phases were attained, allowing for a wide range of mechanical and electrochemical properties to be achieved. The corrosion behavior of studied alloy was evaluated in Ringer’s solution at 37°C using open-circuit potential-time and potentiodynamic polarization measurements.
