| 摘要 |
An inorganic fiber-reinforced metallic composite material comprising a matrix of a metal or its alloy and inorganic fibers as a reinforcing material, characterized in that (a) the inorganic fibers are inorganic fibers containing silicon, either titanium or zirconium, nitrogen and oxygen and being composed of (i) an amorphous material consisting substantially of Si, M, N and O, or (ii) an aggregate consisting substantially of ultrafine crystalline particles with a particle diameter of not more than 500 ANGSTROM of Si2N2O, MN, Si3N4 and/or MN1-x, and amorphous SiO2 and MO2, provided that in the above formulae, M represents titanium or zirconium, and x is a number represented by 0<x<1, or (iii) a mixture of the amorphous material (i) and the aggregate (ii), and (b) said metal is selected from the group consisting of aluminum, magnesium, and titanium, or (c) said alloy is selected from the group consisting of aluminum alloys, magnesium alloys and titanium alloys.
