Description
Summary:The semi-solid antiburning AZ61-1.0%Y magnesium alloy slurry with fine circular solid phase was fabricated by a novel type continuous mechanical stirring in this work.The microstructure of the semisolid slurry was characterized by a metallography microscope.The results show that the fine circular solid phase distributes uniformly in the slurry when the stirring temperature ranges from 600 to 605℃.With the increase of the stirring velocity,the size of the solid phase becomes smaller and smaller.With the increase of the stirring time,the size of solid phase gets finer,but if the stirring time is longer than the critical time,it will be coarsened abnormally.The mechanical properties of semi-solid AZ61-1.0%Y alloy are superior to those of the normally casting magnesium alloy.
