This paper investigates the feasibility of room temperature plastic deformation of pure magnesium through a method of severe plastic deformation (SPD), namely simple shear extrusion (SSE). Different SPD techniques were performed at room temperature and SSE was considered as a promising technique for deformation of magnesium at room temperature. An extrusion process was performed prior to SSE technique to change the initial grain size and texture in the samples. In addition, the effect of different extrusion temperatures and processing strain rates were also studied and a procedure was presented for successful SSE processing of magnesium at room temperature. Finally, the effect of these processing conditions on hardness and microstructural evolutions were investigated. (c) 2012 Elsevier B.V. All rights reserved.
