抄録

A new type fabrication process for particles dispersed composites, powder liquid forming technique, was proposed. In this process, first compacts blended of air atomized aluminum alloy powders and ceramic particles were produced by cold press. The obtained compacts were heated up to the melting point of matrix aluminum alloy and pressed in the mold in order to wet between the molten metal and the ceramic particles, and then formed under pressure. The fabrication conditions of this process were investigated mainly from the density and Vickers hardness of Al₂O₃ particles/6061 powder composites. The forming temperature needed over the melting point of matrix and the forming pressure over 80MPa. 0.2% proof stress increased with volume fraction of Al₂O₃ particles. The elastic moudulus of T6 heat treated Al₂O₃ particles/6061 powder composites, E_c, could be expressed as<br>E_c=178V_f+72(GPa)<br>where V_f is the volume fraction of particles.
