Modern bainitic steels derive their favourable properties, from a mixture of ultra-fine bainitic ferrite with evenly distributed second phases. In order to obtain the desired bainitic microstructure, alloying elements must be used to separate the bainitic C-curve to make it easier to obtain the desired microstructure on cooling. The selection of alloying elements is difficult, as bainitic hardenability has not been studied as extensively as martensitic hardenability.
This project will develop a new "bainitic hardenability" model for optimum selection and flexible replacement of expensive or strategically sensitive alloying elements in high and ultra-high strength steels.
