Inverse Slip Accompanying Twinning and Detwinning during Cyclic Loading of Magnesium Single Crystal

Figure 4

(a) Stress-plastic strain hysteresis loops at the critical points of the first and second loading cycles. In situ, optical micrographs at critical points ( , , , , , and ) show the morphology change of twins. from (b) to (e) illustrate the variations of (b) plastic strains, (c) plastic strain rates, (d) absolute activity of twinning and slip which indicates the percentage of plastic deformation by twinning or slip during a deformation segment in the stress-plastic strain hysteresis loop, and (e) the stress with respect to the time for the first and second loading cycles.
