The textured microstructures in as-solidified grain refined Ti44Al8NbxB (x = 0.1-1) were formed by β phase transforming into Burgers α during solid-phase transformation. The Burgers α volume fraction was determined using electron backscattering diffraction texture analysis. It is related to the boron concentration in the alloys and decreases with increasing boron concentration. This trend can be associated with the formation of more boride precipitates from the liquid in alloys with a high boron concentration.
