Third-generation advanced high strength steels (3G AHSS) are under development to reduce the weight of vehicles in order to improve their fuel efficiency without compromising passenger safety. This study will examine the development of microstructure and mechanical properties of a prototype TRansformation-Induced Plasticity (TRIP) 3G AHSS with composition of 0.15C-6Mn-1Si-1Al-0.5Cr. Heat treatments consisting of intercritical annealing and overageing stages compatible with the continuous galvanizing process were investigated in terms of their effects on the microstructure and the mechanical properties of these alloys. This paper will discuss the results of the thermal processing of this prototype 3G alloy in terms of the resultant microstructures and mechanical properties within the context of established 3G properties.
