TiB_2 parti-cles may form in TiAl matrix at temperatures even below 700℃ owing to the exothermic reac-tion between Ti and Al powders. TiB_2 particles are very thermally stable, and almost no morechanged in their relative amount, morphology and size after the synthesized composite beingremelted. In addition, the existence of TiB_2 particles may be obviously affected on refinementof as-cast TiAl-base alloy microstructure.
