Abstract

Ti-37Al-B alloys were produced by in-situ synthesis method. The phase constituent and the microstructure were studied by XRD and SEM. The results show that the borides in Ti-37Al-B alloys evolve from fibrous TiB to fibrous TiB+coarse TiB and eventually to fibrous TiB+coarse TiB+blocky TiB₂ as the B content increases. The eutectic TiB is fibrous and the primary TiB is coarsely needlelike, but the TiB₂ particles exhibit hexagonal prism morphology. The solidification paths also were analyzed.
