摘要: The influence of the stress state on twinning rate and work hardening is studied in case an Fe-Mn-C TWIP steel strained uniaxial tension, simple shear rolling. resulting stress-strain responses exhibit marked differences. rate, number activated systems each grain, twin thickness transmission twins across grain boundaries are dependent imposed during straining. Relationships between features macroscopic established. © 2012 Acta Materialia Inc.
