摘　　要：采用Al-10%Sr,在800℃下对ZL102进行变质处理,获取了变质剂的加入量及保温时间对ZL102铸态力学性能的影响。总体上看,与740℃下的变质相比,变质效果的变化趋势相似,随保温时间延长先升高后下降,但最佳变质效果明显变差。ZL102采用Al-10%Sr变质处理的最佳保温时间在30 min左右,提高温度对于净化改善合金液具有重要作用。The effects of Al-10%Sr addition and holding time on as-cast mechanical properties of ZL102 alloy at 800℃ were investigated. The modification effect as a whole increases firstly and then decreases with extension of holding time, which is similar with the modification effect at 740℃. But the best modification effect is deteriorated obviously. The optimum holding time for ZL102 modified by Al-10%Sr is about 30 min. The elevated temperature plays an important role in purifying and improving alloy melting.
