Impact of Thermal Conditions on Predicted Formability of TRIP Steels

To improve vehicle fuel economy and improve safety, automakers have focussed on substituting low-carbon steel for advanced high-strength steel (AHSS) alloys. A common grade of AHSS is the transformation-induced plasticity (TRIP) steels, which undergo a phase transformation from austenite to martensitic that enhances the ductility and strength. This work employs a phenomenological constitutive model for TRIP 800 steel to study the …
