ABSTRACT

An impact test was conducted on a single crystal of an Fe–3mass%Al alloy with a bcc structure. Microstructural changes in the sheared regions resulting from the impact test were examined. Deformation twinning was observed, with the twinning plane K1={332} and the twinning shear direction η1=113¯. The conjugate twinning direction η2 of this mode was discussed. Considering the shear direction required to induce deformation twinning, it can be concluded that η2=110 is appropriate for the twinning mode in the Fe–3mass%Al.
