Microstructures of TiC-A12O3-Fe Composites Prepared by SHS/PHIP

Abstract

Abstract: The microstructure of TiC-Al₂O₃-Fe composites prepared by SHS/PHIP was studied. As the Fe content was increased, the particle size of TiC decreased, and the distribution of Al₂O₃ became homogeneous. There existed a little of particle phase in TiC grains. While some of ε- (AlTi)Fe₃C_x cellular phase with -AlFe₃C_0.69 structure was found in Fe-binder phase. A great deal of dislocation were observed in TiC grains because of the rapid pressing in the process of SHS/PHIP.

Key words: SHS/PHIP, TiC-Al₂O₃-Fe composites, microstructure, cellular structure
