an aggregate of iron carbide and ferrite, formed from austenite below the temperature at which pearlite forms and above that at which martensite forms.
Origin: 1930–35; after Edgar C. Bain (1891–1971), American physicist and metallurgist; see -ite1
a mixture of iron and iron carbide found in incompletely hardened steels, produced when austenite is transformed at temperatures between the pearlite and martensite ranges
[C20: named after Edgar C. Bain (1891--1971), American physicist; see -ite1]
