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 993 K, pressure of 27 MPa and time of 4.8 ks in a low vacuum of 1 × 10 2 Pa using a 0.1 mm thick insert was obtained in the experimental range. Curvature of the composite monotonously changes with increasing temperature up to and higher than 1 200 K. A cyclic heating was also performed on the composite by increasing the maximum temperature from 373 K up to 1 273 K in 100 K steps, and it was found that its curvature change has no hysteresis up to 673 K, and has hystereses but is reproducible at 773 K and 873 K. and is no longer reproducible when heated up to 973 K and above.
