Improved formability of Mg–3Al–1Zn alloy by pre-stretching and annealing

Effect of the final rolling speeds on the stretch formability of AZ31 alloy sheet rolled at a high temperature

“…It means that the stretch formability of the sheet at room temperature is more sensitive to the YS, YS/UTS, r-value and n-value than to FE, which is similar with the results of ref. [28]. It is well known that the smaller YS and YS/UTS of the sheet indicate that the sheet possesses the larger uniform plastic deformability, which is beneficial to the enhanced resistance to rupture of the sheet during stamping.…”

Effect of twinning and detwinning on the spring-back and shift of neutral layer in AZ31 magnesium alloy sheets during V-bend

“…Wang et al [6] indicated that the twins generated by pre-compression along extrusion direction disappeared after inverse tension which resulted in improvement of plasticity in an AZ31 magnesium alloy. Zhang et al [7] also proved that the basal texture was weakened by pre-stretch deformation and that the formability of the AZ31 magnesium alloy sheet was improved.…”

Improving tensile and compressive properties of magnesium alloy rods via a simple pre-torsion deformation

“…In recent years, tailoring the microstructure and mechanical properties of magnesium alloys via pre-strain at room temperature has received increasing attentions owing to their low cost [13][14][15][16][17][18].…”
