Bainite

An austenitic transformation product found in some steels and cast irons; it forms at temperatures between those at which pearlite and martensite transformations occur; the microstructure consists of alpha-ferrite and a fine dispersion of cementite.

This term is used by metallurgists to describe a particular structure of steel when the steel is polished, etched and examined with a microscope.
