Title : Extrusion, Microstructure and Mechanical Characterization of a New Magnesium based Multicomponent Alloy


A new magnesium multicomponent alloy Mg70Al18Zn6Ca4Y2 (atomic pct.) synthesized using the technique of Disintegrated Melt Deposition was hot extruded. The extruded samples were characterized in terms of density, hardness, and microstructure. Investigations were carried out to account for compressive properties by testing the samples using a strain rate of 5 X 10-3 per minute. Scanning electron microscopy (SEM), energy dispersive x-ray (EDX) analysis and x-ray diffraction (XRD) analysis were used to examine the presence and formation of phases and microstructural evolution. Hardness tests were used to determine the mechanical properties of the extruded rod. Significantly high microhardness (170 HV) and macrohardness (75 HRB) values were realized in the extruded samples of the said alloy. The measured hardness values in the extruded sample of this alloy were much higher as compared to its corresponding as-cast material.
Keywords:   Magnesium Alloy, Microstructure, Mechanical Properties, Extrusion.
Audience Takeaway:
This new Magnesium based Multicomponent Alloy has shown excellent qualities as compared to commercial Mg Based Alloys.
Being lightweight and exhibiting excellent hardness and compression properties, this material has possible applications in automotive industry to increase fuel efficiency and also  reduce GHG emissions.


Ms. Anchal Nahata is currently pursuing B.E. in Mechanical Engineering from Bits Pilani Dubai Campus. She first started researching on materials when she joined Dr. Manoj Gupta’s group in NUS, Singapore. She has been continuing her research on Magnesium based alloys under her Research Advisor Dr. Vincent Shantha Kumar. She has published an article in the journal Materials Today: Proceedings.
