Technical Paper


Magnesium alloys are important lightweight materials, enabling improved fuel efficiency and reduced emissions in automotive and aerospace industries. Heterogeneous nucleation and effective grain growth restriction during the solidification of these alloys result in enhanced mechanical properties. These can be achieved via the addition of suitable inoculants to the alloy, yet the selection of a potent grain refiner is often challenging and is, therefore, the subject of much research. Mathematical models can be used for the identification and development of effective refiners, subject to appropriate validation. This study examines the grain-refining efficiency of innovative magnesium inoculants via lattice disregistry calculations and presents experimental verification for the models in permanent mould castings.
