AbstractDuring the decomposition of austenite to ferrite in certain iron-base alloys a new form of precipitation has been observed at the ferrite/austenite interface. In appropriate alloys, V4C3, Mo2C, and Cr7C3 form very fine particles on the interface, which repeatedly moves on to provide fresh sites for further nucleation. The transformation leads to a very fine banded dispersion of carbide in ferrite having striking morphological differences from the same carbides in tempered martensite.
