主 题：Magnesium alloys Purification Impurity Melt Iron Silicon
摘 要：A novel low-cost method for melt purification of magnesium alloys,the melt self-purifying technology(MSPT),has been developed successfully based on a low temperature melt treatment(LTMT)without adding any *** iron solubility in the molten liquid of magnesium and its alloys,and the settlement velocity of iron particles were *** is shown that the low temperature melt treatment is an effective method to decrease the impurity Fe content in magnesium and its *** any additions,the Fe content in the AZ31 alloy was reduced to 15 ppm from the initial 65 ppm,and the Fe content in the AZ61 melt was decreased to 20 ppm from the initial 150 ppm after the low temperature melt *** results also showed that the Fe content in AM60 and AM50 dropped to 15 and 18 ppm,respectively,from the initial 150 ppm after the low temperature melt *** ZK 60,the Fe content in the melt down to less than 5 ppm was *** the low temperature melt treatment,the Si content in the above alloys was also decreased obviously.
