TiC/2618 composite was prepared by XD method .The constituent and microstructure of the composite have been investigated by X ray diffraction and TEM technique. The aging characteristics and mechanical properties at high and room temperatures were studied. The results show that: 1) it is possible to prepare multiple alloy matrix TiC/2618 composite by XD method; 2) the TiC particles in TiC/2618 composite have the characteristics of fine size, clean appearance and a good bond with the matrix; 3) the aging law of the TiC/2618 composite has been changed by the addition of TiC particles. Two peak value phenomenon has been observed when it was aged at 190?℃; 4) TiC/2618 composite has better mechanical properties than those of the matrix both at room and high temperatures.
