Microstructure of the Ti3Al(Nb)/TiB composite produced by combustion synthesis

The combustion synthesis technique was used to produce the intermetallic composite α2-Ti3Al(Nb) reinforced with TiB fibers. The microstructure was examined by scanning electron microscopy (SEM), X-ray diffraction analysis, and transmission electron microscopy (TEM). Neither the β nor the β0 phase was found in the intermetallic matrix. The TiB phase with B27 structure existed in the form of polycrystalline faceted whiskers growing in the (010) …
