| Abstract Scope |
Nanostructured bainitic steels have a superior combination of wear, strength, and toughness imparted by fine nanoscale bainitic ferrite/austenite features, which makes them ideal material for high wear service conditions. However, these classes of steels require a very long isothermal heat treatment at low temperatures to form the nanostructure. This talk will focus on presenting a novel design methodology incorporating CALPHAD and machine learning approached to design new alloys that have an accelerated nanostructured bainite formation kinetics. Results on the validation of the down selected alloys using a combination of microscopy techniques and mechanical property evaluation will be presented. The structure and properties of the novel alloys will be compared with baseline alloys reported in the literature. |
