摘要: Abstract Severe deformation by differential speed rolling (DSR) with a high-speed ratio could be successfully imposed on the AZ91 plate to produce thin sheets submicron grain size and good planar isotropy. The exhibited combination of high strength ductility, showing yield stresses ∼327 MPa tensile elongations 9–11%. Comparison other severe processes indicates that DSR process is advantageous over ECAP in obtaining higher ARB ductility. Moreover, current continuous as well convenient method imposing Mg sheets.
