Generally, it is difficult for an intermetallic compound to work the cold working, because of its high hardness, and brittleness in normal temperature. Moreover since the fusing point is high, there are many problems, such as a mold life, a fluidity and so on, even the intermetallic compound is formed by the casting method. However intermetallic compound can be formed easily using Semi-solid processing. In this research, the mechanical strength properties of intermetallic compound in the normal temperature and the elevated temperature were investigated. From the results, it was understood the alloy which consists of Al_3Ni_2 and Al_3Ni is brittle in the both of normal temperature and elevated temperature while the alloy which consists of Al_3Ni and eutectic crystal shows high ductility.
