利用IBAS 1型图像分析仪 ,研究了不同变质剂处理的ZL10 1合金在热处理时共晶硅的粒状化效果 ,结果表明 :变质可有效地促进共晶硅的粒状化 ,不同的变质剂对ZL10 1合金共晶硅粒状化的作用是不同的 ,按促进共晶硅粒状化能力的大小顺序排列为 :复合变质 >Na或Sr变质 Sb变质 The IBAS 1 image analyzer was used to study the grain refinement of eutectic silicon during the heat treatment of ZL10 1 alloy treated with different modifiers. The results show that the modification can effectively promote the granularization of eutectic silicon. 1 alloy eutectic silicon granulation of the role is different, according to promote eutectic silicon granular ability of the order of the order: compound metamorphism> Na or Sr metamorphic Sb metamorphism
