Abstract: Magnesium and its alloys with severe plastic deformation
(SPD) techniques are more attractive as structural parts in many industrial
applications because of their advantages. In this paper, the importance of
wrought magnesium alloys with their applications to accomplish the essential
development of components is reviewed. In addition, the different approaches
of equal channel angular pressing (ECAP) process for refining the grain size to
achieve the ultrafine grained material on the bulk metals are discussed. Recent
developments in the ECAP process are outlined clearly with their importance to
overcome many complexities. Various factors like processing temperature of a
specimen, die geometry, ram speed, back pressure and processing routes
influencing during ECAP process of wrought magnesium alloys at different
conditions such as channel angle and corner or outer arc angle are discussed.
Finally, the properties of ECAP processed wrought alloys are outlined for
improving the microstructure in structural parts.
Keywords: severe plastic deformation; SPD; equal channel angular pressing;
ECAP; wrought magnesium alloys; grain refinement; mechanical properties.
