Abstract
In order to produce easily and at low cost a metallic composite material incorporating metal carbide particles dispersed therein such that fine TiC particles and/or ZrC particles are uniformly dispersed in a matrix of Al or Al alloy, first, a pellet (16) is formed from Ti powder and/or Zr powder (10), graphite powder (12) and Al or Al alloy powder (14), then the pellet is infiltrated with molten Al or Al alloy, and thereafter the pellet is heated up to 1000.degree.-1800.degree. C. in an inactive atmosphere, so that TiC particles and/or ZrC particles are generated in the pellet. Then the pellet is dissolved in a molten bath of Al or Al alloy.
