An evaluation of formability using micro-embossing on an ultrafine-grained magnesium AZ31 alloy processed by high-pressure torsion
An evaluation of formability using micro-embossing on an ultrafine-grained magnesium AZ31 alloy processed by high-pressure torsion
An ultrafine-grained (UFG) magnesium AZ31 alloy was achieved with an average grain size of ?200?nm by high-pressure torsion (HPT) at room temperature (RT) under a pressure of 6.0?GPa through 5 turns. Micro-embossing tests were conducted in a V-groove die having a width of 100??m in the temperature range of 298 to 523?K. The formability of UFG AZ31 alloy was evaluated by measuring the percentage of material flowing into the V-groove. The results show that refinement of grain size can significantly improve the formability by increasing the stain rate sensitivity by comparison with the as-drawn AZ31 alloy. The results demonstrate that the UFG AZ31 alloy exhibits excellent formability for fabricating MEMS components with complicated structures.

Abstract
An ultrafine-grained (UFG) magnesium AZ31 alloy was achieved with an average grain size of ?200?nm by high-pressure torsion (HPT) at room temperature (RT) under a pressure of 6.0?GPa through 5 turns. Micro-embossing tests were conducted in a V-groove die having a width of 100??m in the temperature range of 298 to 523?K. The formability of UFG AZ31 alloy was evaluated by measuring the percentage of material flowing into the V-groove. The results show that refinement of grain size can significantly improve the formability by increasing the stain rate sensitivity by comparison with the as-drawn AZ31 alloy. The results demonstrate that the UFG AZ31 alloy exhibits excellent formability for fabricating MEMS components with complicated structures.
