Abstract Scope |
Safety, environmental preservation and cost effectiveness are important driving factors for innovation in the automotive industry. Together, they drive the demand for higher strength structural metallic alloys with low production costs for the creation of parts with reduced weight. This demand is being answered by the development of Advanced High Strength Steels (AHSS) with novel alloying and processing strategies. The present work investigates the processing of AHSS steel with focus on the production of a Complex Phase (CP1200) steel, with tensile strengths greater or equal to 1200 MPa and mixed microstructures that may contain small amounts of martensite, retained austenite, and pearlite within a ferrite/bainite matrix. Continuous cooling transformation (CCT) diagrams were developed from microstructures produced by thermal treatments performed with a DIL805 quenching dilatometer. Samples were characterized by optical and electron microscopy, and mechanical properties were determined from hardness measurements of laboratory and industrial scale samples. |
