Abstract
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 PA0 (a) the inorganic fibers are inorganic fibers containing silicon, either titanium or zirconium, nitrogen and oxygen and being composed of PA1 (i) an amorphous material consisting substantially of Si, M, N and O, or PA1 (ii) an aggregate consisting substantially of ultrafine crystalline particles with a particle diameter of not more than 500 .ANG. of Si.sub.2 N.sub.2 O, MN, Si.sub.3 N.sub.4 and/or MN.sub.1-x, and amorphous SiO.sub.2 and MO.sub.2, provided that in the above formulae, M represents titanium or zirconium, and x is a number represented by 0<x<1, or PA1 (iii) a mixture of the amorphous material (i) and the aggregate (ii), and PA0 (b) said metal is selected from the group consisting of aluminum, magnesium, and titanium, or PA0 (c) said alloy is selected from the group consisting of aluminum alloys, magnesium alloys and titanium alloys.
