This paper describes fabrication of an active metal-matrix composite working at elevated temperatures. To realize this material, a SiC fiber reinforced nickel layer was laminated on a unreinforced nickel one with an aluminum insert. Fabrication condition of this material was examined and the most appropriate one, that is, hot-pressing temperature of 993K, pressure of 27MPa and time of 4.8ks in a low vacuum of 1×10^2 Pa using a 0.1mm thick insert was obtained in the experimental range. Curvature of the composite monotonously changes with increasing temperature up to and higher than 1200K. A cyclic heating was also performed on the composite by increasing the maximum temperature from 373K up to 1273K in 100K steps, and it was found that its curvature change has no hysteresis up to 673K, and has hystereses but is reproducible at 773K and 873K, and is no longer reproducible when heated up to 973K and above.
