The in-situ TiAl matrix composites with nominal compositions of Ti-44.5Al-8Nb-0.8Mo-0.1B-xC (at.%), where x is ranging from 1.4 to 4.8at.%, were prepared by casting. The microstructure of the as-cast composites consists of primary (Ti,Nb)2AlC particles distributed in the matrix composed of lamellar γ(TiAl)+α2(Ti3Al) and γ phase regions with a small amount of β/B2 phase. The chemical composition of...
The softening produced by microstructural instabilities of an investment cast TiAl-based turbine blade during annealing up to 7300 h is studied. The kinetics of softening are found to be faster than that expected from simple phase transformations and/or coarsening processes controlled by diffusion of Ti or Al in TiAl or Ti 3 Al. The softening at 700 o C is very slow and cannot affect...
