Boride formation behaviour and their effect on tensile ductility in cast TiAl-based alloys [PDF]

Materials & Design, 2020
Boron has been used to refine the microstructures in TiAl castings, such as low-pressure turbine (LPT) blades, to improve mechanical properties. However, boride precipitates with undesirable morphologies could reduce ductility and even entirely remove ...
