General use steels - Classification and metallurgy

thermomechanical treatments; thermomechanical treatments

Rolling and post-rolling cooling technique using temperature controls during successive deformations to develop structural grains and obtain high properties at the end of cooling.

multiphase structures; multiphase steel

Heat treatment of mixtures of phases other than ferrite-perlite with 2, 3 or more components, such as ferrite-martensite, ferrite-bainite-martensite, bainite-martensite-residual austenite, etc.

interstitial free steel; ferrite sans intersticiels

Ferritic structure with very low or ultra-low carbon content, all of which is fixed by titanium or niobium in the form of carbides.
