Summary The temperature dependence of stress in TiAl has been studied in materials processed via rapid solidification. Both the microhardness and tensile tests showed monotonically decreasing stress with increasing temperatures in alloys ranging from 46 to 60 Al. The result agrees with that of Lipsitt et al., but contrasts with that of Kawabata et al., who reported a positive temperature dependence in TiAl single crystals. Subtle material differences in phase, microstructure, and interstitial content are suggested as possible causes for the discrepancy in results.
