Precipitation of Vanadium Carbide on Stacking Faults [PDF]

open access: yesNature, 1965
THE precipitation of niobium carbide and titanium carbide in association with stacking faults in austenitic steels has been widely reported in the literature1–4. During the course of an examination of precipitation in high-alloy austenitic steels we have observed the precipitation of the vanadium carbide, V4C3, also in association with stacking faults.
