Size evolution of the unmelted phase during injection molding of semisolid magnesium alloys

摘要

A size of the unmelted phase within injection molded Mg-Al-Zn alloy depends on the solid/liquid ratio and the smallest particles are generated at very low liquid contents. For high liquid fractions the reduction of the solid content is mainly accompanied by a reduction in the number of particles, while their size is only slightly decreased.
