PURPOSE: To produce a fiber-reinforced metal composite material having high specific strength, specific rigidity, strength and wear resistance by using an amorphous high-strength heat-resistant alloy as the matrix metal and an inorg. fiber consisting of Si, Ti, C, O, etc., as the reinforcement.
CONSTITUTION: An amorphous high-strength heat-resistant alloy shown by formula AlaPbQc or the composite of the amorphous alloy and the microcrystalline alloy is used as the matrix metal. In the formula, P is ≥1 kind of metallic element selected from Y, lanthanoids, and misch metals, Q is ≥1 kind of metallic element selected from Fe, Ni, Co, Cu and Zn, (a), (b) and (c) are atom%, 10≤a≤90, 0.5≤b≤80 and 5≤c≤55. An amorphous continuous inorg. fiber consisting of Si, M (Ti or Zr), C and O is used as the inorg. fiber. The fiber- reinforced metal composite material is produced by the matrix metal with the inorg. fiber as the reinforcement, and the composite material excellent in mechanical characteristics is obtained.
