PROBLEM TO BE SOLVED: To provide a method for producing a composite metallic material which can control the dynamic elastic modulus of a composite metallic material, and to provide a composite metallic material. SOLUTION: The method for producing a composite metallic material comprises steps (a) to (c). In the step (a), carbon nanofibers are mixed into an elastomer, and also, are dispersed by shearing force, so as to obtain a composite elastomer A. In the step (b), the composite elastomer A is heat-treated, and the elastomer comprised in the composite elastomer A is decomposed and vaporized, so as to obtain a carbon based material. In the step (c), within a furnace 50 continuously fed with a nitrogen gas, melted aluminum B is infiltrated into the space of the carbon based material, and is thereafter solidified. In the step (c), the flow rate of the nitrogen gas fed into the furnace 50 is controlled. COPYRIGHT: (C)2009,JPO&INPIT |
