Abstract
A high-rigidity composite material having a Young's modulus larger than 25,000 kgf/mm.sup.2 is disclosed, in which particles are dispersed in a matrix of a ferritic steel, and the degree of accumulation of {111} planes in a plane perpendicular to a given direction, in terms of X-ray diffraction intensity, is 30 times larger than that of equiaxial polycrystals.
