The effect of alloying elements on the oxidation kinetics of commercial titanium alloys, VT1-0, OT4-1, PT7-M, VT5-1, VT14, and VT23, during continuous heating in air up to 1000 C is investigated experimentally using a derivatograph. It is found that Al can either accelerate or retard oxidation, Zr, Mo, and Sn improve the heat resistance of the alloys. Mn has practically no effect, and Cr increases the oxidation rate. At the stage of accelerated oxidation, Mo, Mn, Sn, and Zr significantly increase the oxidation rate of the alloys. However, the oxidation rate of VT14 and PT7-M remains lower than that of commercially pure titanium.
