WebMar 11, 2015 · In magnesium alloys, the typical grain size range usually obtained by static recrystallization is 8-25 µm [23]. Cold hydrostatic extrusion, followed by low-temperature annealing, can produce... WebRotating backward extrusion (RBE) is one of severe plastic deformation (SPD) methods used to produce cylindrical components with a very large strain by a single pass. In this study, the microstructure and texture evolution in the different regions of Mg-12Gd-4Y-2Zn-0.5Zr (wt.%) alloys via RBE process were investigated by using optical microscopy (OM), …
