A Comparative Study of MgY Zn Rod Produced by Different Routes Using Severe Plastic Deformation

Abstract

Ternary Mg Y Zn alloys have attracted considerable attention due to their excellent mechanical properties and unique microstructures. Microstructural variation and the resulting mechanical properties can be affected by various processing routes, particularly those involving severe plastic deformation of a cast billet. The following approach was used in this work to perform a comparative study: Cast Mg92Y4Zn4 billet was subjected to severe plastic deformation by three different routes, namely ECAP, high pressure torsion (HPT) and ECAP followed by HPT with the aim of refining the microstructure. The effect of the processing route and the process parameters on the microstructure and the hardness of the Mg-Y-Zn alloy will be reported.
