• OS0309 Effect of twinning of stress axis and twin interface introduced by pre-straining of Mg alloy Single crystals

抄録

Twinning behavior of Mg-Zn alloy single crystal is investigated. It was found that both the work-hardening rate and the number of serration in the stress strain curve of the specimen depends on the stress axis ([1010] or [1120]) by which the number of operative twi systems changes. In order to understand the effect of grain boundaries on the twinning in Mg alloys, twin boundaries are introduced to single crystal specimens as pseudo grain boundaries. Using EBSD analysis, the importance of the strain compatibility at grain boundaries for introducing twins is confirmed by examining the microstructure evolution of the specimens with pseudo grain boundaries.
