Criticisms of reports that ferrite laths have a sessile interfacial structure are refuted. A local lattice correspondence, achieved across coherent regions between interfacial defects, suffices to produce surface reliefs and martensitic crystallography [Prog. Mater. Sci. 42 (1997) 101]. However, formation of tent-shaped surface reliefs by monocrystalline laths/plates is inconsistent with martensitic growth.
