The generation of reliable data in the high cycle fatigue domain is crucial to support further metallurgic developments optimized steel grades. Commonly employed for this aim, traditional standardized characterization methods are expensive and time-consuming. Thus, circumvent these limitations, different accelerated testing methodologies have been proposed. In work, rapid test based on stiffnes...

The microstructural evolution, deformation mechanism and mechanical properties of Fe-25Mn-3Si-3Al-0.3Nb steel in the process cold rolling were studied by optical microscopy, scanning transmission electron X-ray diffractometry, tensile testing microhardness tests. A high-density dislocation structure a small number strain-induced twins appeared microstructure at 30% strain. At 50% strain, austen...

The elementary mechanisms controlling the interactions between lattice gliding dislocations and twin boundaries were carefully analyzed using conventional and advanced transmission electron microscopy techniques in both bulk coarsegrained Fe-Mn-C TWIP steels with deformation twins and nanocrystalline Palladium thin films with nanoscale growth twins. The results reveal that the individual disloc...

Abstract In this study, the hot rolled medium manganese steel containing titanium was solution treated at 1,000 °C and followed by aging treatment 500, 550, 600 °C. The influence of on mechanical properties wear resistance reinforced with Ti(C,N) particles investigated. It found that matrix austenite. austenite grain size refined, were precipitated after treatment. Compared to as-hot sample, in...

Due to pronounced work-hardening induced by the complex interplay of deformation mechanisms such as dislocation slip, twinning and/or martensitic phase transformation, high-manganese steels represent a class materials well-suited for mechanical surface treatment. In present study, fatigue behavior high-mangsanese steel showing twinning-induced plasticity (TWIP) effect at room temperature (RT) w...
