Abstract: The aim of this paper is to investigate the influence of different thermo-mechanical processing (TMP) parameters on the fracture plasticity (total elongation to failure) of a novel near β alloy Ti-20.6Nb-13.6Zr-0.5V (TNZV). The TMP scheme comprised of hot working above and below β phase, solutionizing treatment above and below β phase coupled with different cooling rates. Factorial design of experiment was used to systematically collect data for total elongation to failure. Validity of assumptions related to the collected data was checked through several diagnostic tests. The analysis of variance (ANOVA) was used to determine the significance of the main and interaction effects. Finally, optimization of the TMP process parameters was also done to achieve optimum values of the total elongation. The results indicated that the working temperature at 850 0C, solution treatment temperature at 850 0C and water quenching is the optimum combination of TMP parameters and their levels to yield the optimum elongation.
