Secondary hardened bainite [PDF]

Materials Science and Technology, 2014
The effect of Mo additions on the development of bainitic ferrite in hot rolled low carbon (0·05 wt-C) Nb containing steel strips has been studied. The steel strips were fabricated by a combined process of controlled rolling and accelerated cooling. Microstructural characterisation and mechanical testing for the corresponding strips were investigated.
