<p>In order to verify the validity of the rank-1 connection model of kink band, a comparison between the kink described by the rank-1 connection and the kink actually formed in LPSO-Mg alloy was made in this study. Crystal rotation and kink interface (vk) of kink bands formed by almost single basal slip were analyzed by EBSD and double trace analysis. Theoretical kink interface (nα) was computed using the experimentally acquired crystal rotation of the kink bands using the rank-1 connection model. A comparison was made between nα and vk. Theory and experiment showed agreement within 4°, indicating that the geometry of the kink band is well described by the rank-1 connection.</p>
