Hot working of intermetallic compound is difficult because of its high mechanical strength at high temperature, but it seems to be possible by the semi-solid processing that is deformed at the slurry state. This study was investigated on formation of the slurry when Al-(40〜44)mass %Ni powder mixture was heated with various heating rates. The slurry forms at low temperature than the melting point of aluminum and this temperature decreases with the slower heating rate. After solidification from the slurry, microstructure of the Al-Ni alloy is constituted of Al_3Ni_2 and Al_3Ni intermetallic phases and eutectic structure. The hot working of Al-Ni alloy with intermetallic composition can be accomplished by the die-casting of backward extrusion type under condition of the slurry state. Al-Ni alloys constituting of Al_3Ni_2 and Al_3Ni intermetallic phases is high strength in both of room and elevated temperatures and the structure of the alloy constituting of Al_3Ni_2 and eutectic structure became to Al_3Ni_2 and Al_3Ni intermetallic phases by the heat-treatment.

由于其高温下的机械强度很高，因此金属间化合物的热量工作很困难，但是由于在浆液状态下变形的半固体加工似乎是可能的。当Al-（40-44）质量％Ni粉末混合物以各种加热速率加热时，研究了这项研究。浆液在低温下的形成比铝的熔点形成，并且该温度随较慢的加热速率而降低。从浆液中凝固后，Al-Ni合金的微结构由Al_3ni_2和Al_3ni金属间相和共晶结构构成。 Al-Ni合金具有金属间成分的热量可以通过在浆液状态下向后延伸类型的模具铸造来实现。构成Al_3ni_2和Al_3ni的Al-Ni合金在房间和升高的温度中都是高强度，而Al_3ni_2和Al_3ni_2和Al_3ni Interylic phass的合金结构构成Al_3ni_2的合金结构。
