Abstract
Spark plasma sintered TiB/Ti-6Al-4V composites have been characterized using scanning electron microscopy (SEM), electron backscattered diffraction (EBSD) and transmission electron microscopy (TEM). As-SPS processed composites exhibit a more refined distribution of equiaxed α precipitates as compared to arc-melted composites containing similar volume fraction of TiB precipitates. Additionally, SPS processed composites also show a highly refined distribution of TiN precipitates, as revealed by TEM studies.
