A process for the manufacture of high-strength materials from metallic polycrystalline filamentary material, e.g. iron, which has been deposited from the gaseous phase, wherein a mass of the filaments is consolidated by deposition of a metal thereon to join and bond the filaments at their points of intersection, whereafter the mass is briefly heated under pressure to produce a diffusion bond between the metal of the filaments and the metal deposited thereon and to compact the mass. Thereafter the mass may be impregnated with a metal of lower melting point. Loose unbonded masses of filaments may be similarly impregnated, particularly if the filaments are given a prior surface treatment to reduce oxidation and so ensure wetting of the filaments by the impregnating metal. Where the impregnating metal forms an alloy with the metal of the filaments, the latter may be provided with one or more intermediate layers of a non-alloying substance. |
