“…As to magnesium alloy, especially AZ31, Barnett and co-authors [8] have arrived at a critical grain size for the transition in Hall-Petch behavior in terms of Zener-Hollomon parameter [20]. According to the critical grain size equation by Barnett, the critical grain size for deformation twinning was 2.304 in our previous study [43]. Thus, deformation twinning could occur in our study.…”

“…To date, numerous studies on magnesium and Mg-alloys tends to focus on the relationship between microstructure and mechanical property [2,7,15,21,43]. Slip [2,26,35] and deformation twinning [5,6,18,38] are two main deformation http://dx.doi.org/10.1016/j.engfailanal.2015.04.020 1350-6307/Ó 2015 Elsevier Ltd. All rights reserved.…”

“…The mentioned phenomenon was also observed in another research work. Yu et al [34] employed ECAP process on AZ31 magnesium alloys. They measured a CYS value 36 MPa larger than the TYS in 4 pass samples, while the TYS was 50 MPa larger than CYS in as-received AZ31 magnesium alloy samples.…”

Modern wrought magnesium alloys have poor formability at room temperature, which impedes the wider uptake of these alloys by the industry. Over the last decades, research activities in the area of magnesium alloy development have grown enormously and have produced a pallet of exciting findings, which the authors summarize in this concise review focused on the effect of the microstructure, primarily of grain size, on room temperature ductility of wrought Mg-based alloys. Well-established paths and modern strategies to control over the grain size distribution are discussed. It is demonstrated that the use of severe plastic deformation techniques for ultimate grain refinement in magnesium alloys opens new windows for improving their mechanical properties profile by managing both strength and ductility in a wide range. However, it is shown that grain size alone cannot be regarded as a key parameter controlling the mechanical behavior of Mg alloys. The effect of texture is of paramount importance for the overall mechanical response of Mg alloys and this may supersede the influence of grain size.
