【Abstract】 A new modification method for aluminium alloy was found based on experiments in which refining modification was performed by adjusting Si content and adding RE,Sr on the matrix of ZL101A alloy.Experimental results showed that the performance of ZL101A alloy modified by this process was superior to that by Ti and Sr and the costs were rather lower.This method was ideal to modify aluminium hub material.更多还原
