摘　　要：研究了铁、锰对ZL108活塞合金铸造性能的影响。试验表明,在磷变质ZL108合金中,随着铁含量的增加,其流动性降低,体收缩、线收缩也减少。在高铁ZL108合金中加入锰后,可提高流动性,因为锰能够抑制针状β铁相的有害影响。This paper deals with the influence of Fe and Mn on castability of ZL108 piston alloy. The experiments show that the fluidity, volume shrinkage, line shrinkage reduced with increase of iron content in ZL108 alloy modified with P. The fluidity becomes better with addition of manganese in ZL108 alloy of higher iron content, this is because pernicious influence of needle-like β iron phase can be reduced by Mn.
