Abstract

Grain refinement is an effective way to improve the mechanical properties of magnesium alloys. However, refining efficiency of grain refiner for Al-containing magnesium alloys is unstable, restricting the further applications in the engineering field. In this paper, a typical Al-containing magnesium alloy (AZ91) was studied. The Al–Ti–C–Y alloy containing multiphase particles (Al4C3, TiC, Al2Y) was prepared by self-propagating high-temperature synthesis (SHS) and melting-casting method. Meanwhile, the size, morphology, and distribution of multiphase particles in the Al–Ti–C–Y alloy and the grain refinement performance of multiphase particles for Al-containing magnesium alloys were investigated. The grain size of the alloys decreases first and then increases with the increasing amount of master alloy added. The highest refining efficiency of Al–Ti–C–Y for AZ91 is 51% with 1.5 wt% master alloy added.
