Abstract

TiC-Ni₃Al composites are under development for application in diesel engines because of desirable physical and mechanical properties. Ni₃Al is capable of being strengthened by solid solution techniques because it can dissolve substantial alloying additions without losing the advantage of long-range order. The intermetallic binder was modified by additions of Fe, Si, Co, Ti, Mo, Cr, or W. Powder compacts with binder contents of 30 vol.% were fabricated by reaction sintering with fine elemental powders to form Ni₃Al alloys in-situ during liquid phase sintering. Fe Si, Co, and Cr are found to remain in the binder phase along with minor amounts of Ti (from dissolution of the TiC). Mo, W, and some Cr precipitate out as complex (Ti_xM_y)C-carbides to form 'rim' structures on pure TiC 'cores.'
