Abstract

The effects of the ferrite/austenite orientation relationship (OR) on interphase precipitation in Fe–0.1C–1.5Mn–0.4V (mass%) alloy were investigated by using electron backscattering diffraction and three-dimensional atom probe. VC interphase precipitation in both sheet-like and random dispersions is obtained in ferrite without a near Kurdjumov–Sachs (K-S) OR with adjacent austenite into which the ferrite grows, while the number density of VC in ferrite with a K-S OR is far lower, indicating that a large deviation from the K-S OR is necessary for interphase precipitation in low-carbon steels.
