High Temperature phase stability in ternary titanium aluminides.
High Temperature phase stability in ternary titanium aluminides [pdf]Paper  abstract   bibtex   
In the development of high temperature intermetallics, it is essential to consider the strong influence of materials processing. Among the fundamental data needed for effective processing are the relevant phase diagrams, the characteristic diffusivities and the possible solidification reaction pathways. In the Ti-Al system recent advances in the clarification of the phase diagram have had a direct impact on the analysis of phase stability and crystal growth process. Building on the binary phase equilibria, it has been possible to develop new insight into several Ti-Al-X (X = Nb,Ta,Mo) ternary systems and the identification of ternary intermetallic phase reactions that are important for strengthening, toughening and creep resistance. Monolithic alloy designs are also being supplemented by intermetallic matrix composites where again phase equilibria and interdiffusion reactions analyzed in diffusion couple studies provide an essential basis for an effective microstructure control and design strategy.
