CONSTITUTION:This alloy is constituted of, by weight, 15 to 25% Si, 3.5 to 6.5% Fe, 0.6 to 2.0% of one of more kinds among Zr, V and Mo and the balance Al and has a structure in which the average size of Si grains is regulated to =15%, its wear resistance and elastic modulus alpha are improved and the coefficient of thermal expansion Ce is reduced, but in the case of >25%, the toughness is reduced. As for Fe, its heat resistance, high temp. strength, alpha and Ce are increased and its ductility and toughness are reduced, but in the case of 6.5%, the ductility and toughness are reduced and the high temp. strength is saturated as well. Zr or the like hardly reduced the toughness and improve the high temp. strength, but in the case of 2%, the reduction of the toughness appears. As for the Si grains, by dispersing them in the above-mentioned manner, sufficient strength and toughness can be obtd.

摘要： PURPOSE:To enable arrangement of the forming material at the prescribed position, by inserting the forming material by using a holding material to hold the forming material, in the method of pushing the porous forming material into the molten metal in a mold. CONSTITUTION:After the molten metal 4 is poured into the mold 3, the holding material 5 is laid on the mold as that its center may be located at the center of the mold 3, and the preform 2 is laid on its central part and pushed down into the mold 3 by the plunger 1. The holding material 5 forms the breaks as spoke-like from the center hole and at the time of pushing down the preform by the plunger 1, the holding material 5 is opened at the breaks and the preform 2 is passed through at the central part of the holding material 5. As a result, the upper face of the preform 2 is closely brought into contact with the plunger 1, and its side face is supported by the supporting part 8 and it is inserted into the molten metal straightly at the center part of the mold 3. Therefore, the preform 2 does not suffer from any deficit by coming into contact with the mold 3.
