摘要：
The influence of thermo-mechanical processing (TMP) on the microstructure and the electrochemical behavior of new metastable beta alloy Ti-20.6Nb-13.6Zr-0.5V (TNZV) was investigated. The TMP included hot working in below beta transus, solution heat treatments at the same temperature and 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 alpha and beta phases were attained, allowing for a wide range of electrochemical properties to be achieved. The corrosion behavior of the studied alloy was evaluated in a Ringer's solution at 37 degrees C via open circuit potential-time and potentiodynamic polarization measurements.
