Summary:The growth of butterfly martensite in an Fe-Ni-V-C alloy was investigated using an optical microscope and transmission electron microscope through observing its morphology. The present butterfly martensite is dislocation-type, with a few fine twins. One wing of a butterfly martensite is layered more heavily than the other and the concave part is layered more obviously than other regions. Most butterfly martensites have a lath plate outside of and next to one wing. The outside martensite plates grow first, and then two wings of butterfly martensite. The smooth parts of a butterfly martensite grow earlier than the layered regions. A wing of a butterfly martensite grows like a group of lath martensites.
