Air Cooling Martensites—The Future of Carbon Neutral Steel Forgings?

Abstract: The air‐hardening ductile forging steels belong to the third generation of advanced high‐strength steels and achieve their final, martensitic microstructure simply by air cooling from the forging heat. The present conference paper reviews the 15 years of development, different alloying strategies, and metallurgical throwbacks like manganese embrittlement. Furthermore, the most recent results concerning microstructure, mechanical properties, and cyclic material behavior obtained from an industrial trial melt ar… Show more

“…[1,2] The application of highstrength steels for automotive body parts will allow to lower the total mass of the vehicle and therefore they will contribute to reducing fuel consumption and the negative impact on the environment. [3] Beneficial mechanical properties of high-Mn steels are attributed to specific deformation mechanisms, which occur beside dislocation slip-transformation-induced plasticity (TRIP) and twinning-induced plasticity (TWIP). The ε hexagonal or α 0 body-centered martensite plates and mechanical twins act as strong barrier for dislocation motion.…”

“…However, their applicability for large wall thicknesses is questionable, as they were designed for automotive applications. For small components, significant reductions in the product's carbon footprint were achieved [6], increasing their sustainability [7].…”

“…The development of new steels with good mechanical properties and high‐fatigue resistance is critical for various industries because it improves the longevity and reliability of structures and components, which consecutively increases the circularity of the steel industry. [ 1 ] Bainitic steels with cost‐effective alloying concepts have attracted significant research attention to fulfil the requirements of many industrial applications. The performance of bainitic steels is highly related to the microstructural constituents and their morphology, which can be tailored by the chemical composition and processing parameters.…”
