        abstract = {Modification of hypereutectic A1-Si alloys was conducted. The influences of Phosphorus (P), on the mechanical properties of alloys were investigated. The complex modifications of  Phosphorus make the coarse block primary silicon obviously refined and the large needle eutectic silicon modified to the fine fibrous or lamella ones. Phosphorus mainly refines the primary silicon, but excess Phosphorus is unfavorable to the refinement of primary silicon. The alloys with the additions of 0.02% P to 0.03 % P have the optimal grain size and the improved mechanical properties, Compared with the unmodified alloy. The hardness is decreased from 81 to 57 by Vickers hardness which in turn increases its plasticity , strength  and  wear  resistance },
