Beta Phase Decomposition in a TiAl Alloy during Continuous Cooling

Abstract:

Article Preview

Beta phase decomposition in Ti-44Al-4Nb-4Hf-0.1Si during continuous cooling from β phase field has been investigated. A wide cooling rate range (0.3-1000°Cs-1) was provided by mainly using Jominy end quenching, which has been introduced into TiAl research recently, together with iced brine quench (IBQ) and furnace cooling (FC). At different cooling rates beta phase decomposes via different paths through diffusion or diffusionless mechanisms and lamellar transformation may occur after β decomposition at certain cooling rates.
