Kikuchi patterns taken from the quenched Fe21Mn58Al17Ni4 alloy. (a) Austenite BKD pattern taken from the region marked with `A' in Fig. 3(c). (b) Martensite BKD pattern from the region marked with `M' in Fig. 3(c). In the following figures, the martensite pattern is shown with indexed polytype-invariant bands (c), bands of the first (major) orientation (d) and the second (minor) orientation (e), and distortions in the shape of certain bands (f). |
