12 - 245Spontaneous Infiltration of Iron Silicides into Silicon Carbide PowderPreforms. — The infiltration of liquid Fe3Si, Fe5Si3, and FeSi into SiCpowder preforms is performed at various temperatures under either Ar flowor dynamic vacuum. Infiltration temperature and amount of infiltration areconsidered and analyzed using IR spectroscopy, SEM, and optical microscopy.Infiltration of fired samples under vacuum at relatively low temperatures cangive very dense and well-bonded SiC particle-reinforced iron silicide-basedcomposites. — (PAN, YI; BAPTISTA, JOAO L.; J.
