Abstract

Ti-48%Al-2%Cr-2%Nb-(0, 0.5, 1)at.%W alloys were synthesized via the powder metallurgical route, and cyclically oxidized at 800, 900, or 1000°C in air for up to 100 h in order to find the effects ofWon their oxidation characteristics. At 800°C, they oxidized relatively slowly, and the scales were thin and adherent. At 900°C, the scales began to spall locally. At 1000°C, they spalled repetitively during oxidation.Cr,Nb, andWimproved the cyclic oxidation resistance of TiAl alloys. The oxides formed wereTiO2andAl2O3, which contained the alloying elements ofCr,Nb, andW. Nitrides formed wereTiNandTi2AlN.
