Prediction of oxidation behavior of near-α titanium alloys

The oxidation behavior of near-alpha Ti alloys with added Al, Ga, Sn, Zr, Mo, Nb, Ta, W, Si, and Ge was analyzed using a regression analysis technique. The regression analysis with the data for oxidation tests at 700 degrees C for unalloyed Ti, 10 binary alloys, and 27 multicomponent alloys showed good correlation with alloy compositions with the squared multiple correlation coefficient, 0.93. The obtained results demonstrate the role of each element in commercial alloys. The effect of microstructure on the oxidation behavior was also discussed. (C) 2016 Elsevier Ltd. All rights reserved.
