Safety regulations and light weight design demands has resulted in increasing application of high strength steels in structural components of an automotive. Ultrafine grained (UFG) steels are expected to be used in the future as structural materials in automotive industry due to unique combination of high strength and toughness, which results in an increase in strength to weight ratio. A number of factors contribute to increase in yield strength during bake hardening which depend on carbon content, alloying elements and manufacturing procedure, hot rolling and cooling parameters, heat treatment parameters, prestrain, aging temperature and time etc. It has been reported in literature recently that bake hardenability is more pronounced in case of ultra fine grain than coarse grain (CG) steel due to lower grain size. In this review, we will discuss various bake hardening mechanisms prevailing in UFG and CG steels.
