New Multiphase CP and DP 1000 MPa strength level grades for improved performance after hot forming [PDF]
, 2019 Pure martensitic steels have after hot forming limited performance in terms of rest ductility which limits the application in crash relevant parts. New steel grades were designed in the EU project HOTFORM including the corresponding process routes. These

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.
