Study of Oxidation Resistance on Ti-Al Alloys : Effect of Heat Treatment and Chromium Addition on the Short Term Oxidation Behavior of Tial-Alloys At 900ºC in Air

Results show that a decrease in Al content resulted in an increase in the amount of alpha2-Ti3Al phase, which led to an increase in the strength of the alloys but gave detrimental effect to the specific weight. In contrast, the higher Cr addition shows an increase in both strength and specific weight of the alloys. In addition, suitable amount of Cr addition (
