A method for the production of metalsecond phase composition materials containing a second phase, said method comprising precipitating at least one second phase material in a metal matrix by contacting reactive second phase forming constituents, in the presence of a substantially non-reactive solvent matrix metal in which the second phase forming constituents are more soluble that the second phase, at a temperature at which sufficient diffusion of said constituents into the solvent matrix metal occurs, to cause reaction of the reactive second phase forming constituents to increase the temperature to a temperature exceeding the melting temperature of the matrix metal, to precipitate the second phase in the solvent matrix metal, rapidly quenching the metal-second phase composite material at a rate in the range of approximately 104°C. per second to 108°C. per second and recovering a rapidly solidified metal-second phase composite material.
