METAL-BASED COMPOSITE MATERIAL AND METHOD FOR PRODUCING SAME

摘要

A metal-based composite material which has a sufficient radiation absorption function, also has excellent strength, corrosion resistance, processability, impact resistance and heat conductivity, and is inexpensive. A metal-based composite material having such a double-clad structure that a core material is sandwiched between a pair of skin materials each composed of an aluminum plate in such a manner that the core material is closely adhered to the skin materials, wherein the core material comprises a matrix produced by consolidating an aluminum powder by applying a pressure and tungsten particles dispersed in the matrix, and wherein the tungsten particles are contained in the core material in an amount of 5 to 70 vol %. A method for producing a metal-based composite material, which comprises filling a mixed powder of an aluminum powder that constitutes a matrix and tungsten particles into an aluminum case and then extending the mixed powder by applying a pressure.

主权项

1. A metal-based composite material of the present invention which is provided with
a core material which is comprised of aluminum powder which is pressed together to form a matrix and of tungsten particles which are dispersed in the matrix and with a pair of skin materials which are comprised of aluminum sheets which are brought into close contact with and sandwich the core material to form a two-sided clad structure, said tungsten particles being contained in said core material in an amount of 5 vol % to 70 vol %.
