| Abstract Scope |
Whilst a number of high Mn TWIP steels and dual phase ferritic/martensitic steels are currently used in energy absorption applications, there has been a resurgence in interest in leaner medium Mn steels to replace these. By controlling the austenite fraction and stacking fault energy through composition, and therefore combining the TWinning Induced Plasticity (TWIP) and TRansformation Induced Plasticity (TRIP) mechanisms, medium Mn steels have shown significant promise for energy absorption applications, in particular those with high strain rates. Whilst a number of these TW/TRIP steels have been successfully developed at the lab scale, they have not yet been widely demonstratable at an industrial scale. In this work we scale up a novel TW/TRIP steel to a 5t ingot and subsequently show the effect of industrial scale thermo-mechanical processing on the consequent energy absorption and deformation behaviour under a variety of strain rates. |
