Abstract
The invention concerns alloys comprising a matrix based on at least one conductor metal M, formed by a homogeneous dispersion in the matrix of stable coherent particles of one or more associations of ions of type M, M', O in which M represents the metal or metals of the matrix, M' represents a different metal from M, which is capable of undergoing internal oxidation, and O represents oxygen. It also concerns the process for the production of such alloys which comprises subjecting a starting alloy powder to the action of an oxidizing agent formed by a powder with a granulometry of the order of 1 .mu.m of a metal oxide capable by thermal decomposition of providing the oxygen necessary for the internal oxidization of M', the starting alloy being based on at least one metal M, if appropriate hardened by one or more elements R or A as defined hereinbefore. Use of such alloys for the electrical, electronic and connection arts.
