TiAl based alloys are currently deployed in extreme service environments, such as jet engine turbine blades. The microstructure of these alloys is a two-phase lamellar structure, comprising of the majority γ-TiAl and the minority α2-Ti3Al phases. Understanding the microstructural evolution at high s...
