Abstract

Ti-11Al alloys with C content up to 1. 5% (mass fraction) were prepared by melt-casting processing. Phase equilibria and TiC transformations were studied using optical and scanning electron microscopy and X-ray diffractometry. As-solidified Ti-11Al alloy with 0. 5%C consists of α-Ti, α₂-Ti₃3 Al and TiC, and with increasing C content, these phases change into α₂-Ti₃ Al, TiC and Ti ₃ AlC, respectively. TiC is in equilibrium with β-Ti at 1 250 °C. However, Ti₃ AlC is in equilibrium with α-Ti and α-Ti+α₂-Ti₃ Al when the alloys are heat treated at 1 050 °C and 750 °C respectively. TiC phase in as-solidified Ti-11Al-1. 5C alloy dissolves and precipitates as thin elongated Ti ₃AlC plates after holding at 1 050 °C and 750 °C for a long time. Thin elongated Ti₃ AlC plates precipitate along specific crystallographic orientation and are parallel to each other.
