Metallurgical Fundamentals of TMP

Oral Presentation

In this study, the room temperature tensile and microstructure evolution of a novel cold-rolled lightweight austenitic steel (Fe–19Mn–6Al-4Ni–1C) subjected to different annealing schedules were investigated by transmission and scanning electron microscopy equipped with electron back-scattered diffraction (EBSD) and room temperature tensile test. All experimental samples were furnace annealed...

Metallurgical Fundamentals of TMP

Oral Presentation

In this study, the experimental procedure involved hot rolling (1100°C–850°C) of six novel lightweight steels from different groups: ferritic, ferrite-based and austenite-based, followed by a heat treatment schedule to achieve the desired mechanical properties and compatibility for an industrial continuous annealing line. The heat treatment consisted of soaking at various temperatures between...

26. Assessing the Role of Retained Austenite Heterogeneity in the Mechanical Properties of Medium-Mn Steels

Metallurgical Fundamentals of TMP

Oral Presentation

Medium-Mn steels are promising candidates for next-generation advanced high-strength steels owing to their exceptional strength–ductility balance. The heterogeneity in retained austenite (RA), particularly in terms of chemical composition and morphology, has sometimes been reported to be beneficial. In this study, this view is critically examined to elucidate the effect of austenite...

27. Mechanical Property Comparison of Bainite-Based and Conventional Quenching and Partitioning (BQ&P vs Q&P) in a Medium-Carbon Steel

Metallurgical Fundamentals of TMP

Oral Presentation

Advanced high-strength steels are widely used in the automotive industry because of their excellent mechanical properties, which arise from their multiphase microstructure and the transformation-induced plasticity (TRIP) effect. Among advanced heat-treatment routes, quenching and partitioning (Q&P) has been extensively developed to produce retained austenite (RA)-containing microstructures...
