摘　　要：The modification effect of CX-type (CX means the modifiers that have longeffective term) modifiers applied in ZL108 and ZL104 Al-Si alloys has been studied in detail. Theresults show that the morphologies of the eutectic silicon and the primary silicon can be modifiedand refined simultaneously. The modification effect acts quickly and can maintain a period of 8 h bythe CX-type modifiers. The CX-type modifiers increase the mechanical properties of Al-Si alloys andimprove the service properties of machine parts made of Al-Si alloys (such as piston and cylinderetc.). In modifying processes, the amount of the addition of CX-type modifiers is smaller than thatof any other modifiers, and the modifying procedures are simple. There are no smoke, no dust, and noirritant smell in modifying processes using CX-type modifiers. Therefore, the CX-type modifiershave advantages in economy and environment protection.The modification effect of CX-type (CX means the modifiers that have longeffective term) modifiers applied in ZL108 and ZL104 Al-Si alloys has been studied in detail.
