Abstract
The crystallographic orientation of TiB is one of the main factors that influence the microstructure and texture evolution of Ti-TiB composites. Different microstructures and textures were obtained by forming the two TiB-TC25G composites through vacuum arc melting and in situ reaction hot pressing. The texture evolution, as well as the role of TiB on the α variant selection and microstructure morphology during the β → α phase transformation in TiB-TC25G composites, are studied using an electron backscattered diffraction analysis method in the present work. It appears that the vacuum arc melting makes the TiB texture sharper and promotes the α variant selection during β → α phase transformation. Moreover, the α/TiB interface structure was characterized via transmission electron microscopy. TiB particles provide heterogeneous nucleation sites for the non-Burgers orientation relationship α phases within both TiB-TC25G composites. A synergetic effect of TiB texture and β texture on the formation of α texture is also discussed.
