High-strain-rate superplasticity and tensile behavior of fine-grained Mg97Zn1Y2 alloys fabricated by chip/ribbon-consolidation

A new combined processing procedure is applied to a Mg97Zn1Y2 alloy with a long-period stacking ordered (LPSO) phase. The procedure involves three processes: cooling-rate-controlled solidification, chipping of the solidified master alloy, and extrusion for chip/ribbon-consolidation. Three types of c...
