Hot working of intermetallic compound is difficult because of its high mechanical strength at high temperature, but it seems to be possible by the forming under condition of solid-liquid state that is formed by heating at fusion temperature of lower melting metal in powder mixture. This study was done on synthesis of intermetallic compound from the solid-liquid state when Al-(40-44)mass%Ni powder mixture was heated with various heating rates. The Al-Ni solid solution forms at lower temperature than the melting point of aluminum and then the solid-liquid state forms with high exothermic heat by fusion of the solid solution. After solidification from this state, microstructures of the Al-Ni alloy are constituted with Al3Ni2 and Al3Ni intermetallic phases and eutectic structure. The same microstructure in the Al-Ni alloy backward-extruded under condition of the solid-liquid state is constituted as the isochronally heated powder mixture.
