Abstract: PURPOSE:To obtain an Mg-base composite material without the mechanical properties being deteriorated due to the entrainment of an atmospheric gas at the time of bringing molten matrix Mg into contact with reinforcement powder to infiltrate the melt into the powder by mixing an infiltration assistant in the reinforcement powder. CONSTITUTION:An infiltration assistant (SiO2, etc.) is mixed with reinforcement powder (of SiC, etc., having about 0.1-100mum grain diameter) so that the obtained mixed powder 2 contains 1-99vol.% assistant, and the mixed powder 2 is placed on the bottom of a steel crucible 1. A matrix alloy consisting of the ingot of Mg or Mg alloy is put on the mixed powder 2, and the crucible 1 is arranged in a high-frequency induction furnace 6, surrounded with a chamber 7 contg. an Ar atmosphere and placed in the atmosphere. The ingot is heated into a melt 3a, the melt 3a is infiltrated into the mixed powder 2 and allowed to react with the infiltration assistant to form magnesium oxide, and an Mg-base composite material wherein the reinforcing grains are dispersed is produced. Consequently, the entrainment of the atmospheric gas is prevented, and an Mg-base composite material without the mechanical properties being deteriorated is obtained.
