Shear banding phenomenon during severe plastic deformation of an AZ31 magnesium alloy

Hardness and microstructure homogeneity of pure copper processed by accumulative back extrusion

“…As the second and third passes are applied, the shear bands already formed during the first pass tend to propagate, causing the region I to spread out. Similar evolution of shear bands structure has been observed for the ABE processing of a magnesium alloy [28]. Moreover, the hardness homogeneity increases since the nondeformed regions diminish, so that an acceptable homogeneity is achieved after the third pass.…”

Enhanced Mechanical and Corrosion Performance by Forming Micro Shear Bands in Cold Forged Mg-Gd-Y-Zr Alloy

“…The micro shear bands observed here are different from the macro shear bands usually observed in hot processed Mg alloy extending across several grains or even nearly the whole processed samples. They are considered to be formed through the sever deformation on the shear plane along the shear direction of sample via twining or twining dynamic recrystallization [ 13 , 14 , 15 , 16 ]. The heavy traces along basal plane and curved feature of the dislocations indicate that the dislocations glide on both the basal and non-basal planes.…”

Grain growth kinetics of bulk AZ31 magnesium alloy by hot pressing

“…Even though magnesium and magnesium alloys have high strength-to-weight ratio, they exhibit low ductility and low strength [1][2][3][4][5]. In this regard, many new methods have been developed to overcome these weaknesses and achieve desired properties [6][7][8].…”
