Abstract
This study reports the influence of the addition of Yttrium (wt.3%) on strain-rate sensitivity of Mg-6Sn alloy. The Mg-6Sn and Mg-6Sn-3Y alloys were made by using high pressure die-cast. The microstructural and X-ray diffraction results exhibited that the Sn3Y5 and MgSnY intermetallic phases were formed with addition of Y to the Mg-6Sn alloy. Furthermore, the grain structure of the Mg-6Sn alloy was changed from dendritic to globular with addition of Y. The strain-rate sensitivity value of the Mg-6Sn-3Y alloy is found higher than that of the Mg-6Sn alloy for all strain value. This result was attributed to the formation of new intermetallics (Sn3Y5 and MgSnY) and microstructure morphology (from dendritic structure to globular).
