Abstract:The TiC/2618 composite has been prepared by XD method. The preparing technology,miscroscopy and the crystallization law of the composite have been studied. The results show that the TiC particles in the composite have the characteristics of fine size (＜1 μm), clear appearance and a good bond with the matrix, and the recrystallization temperature of the composite increases about 50 ℃ in comparision with that of the 2618 alloy.
