Enhancement of grain structure and mechanical properties of a high-Mn twinning-induced plasticity steel bearing Al–Si by fast-heating annealing

Impact of Ultra-Flash Tempering Treatment on the Microstructure and Mechanical Properties of High-Strength Carbon Steel

“…The results showed that the grain structures processed by the applied route exhibit a significant mechanical performance and high stretch formability. Khosravifard et al [18] employed a Gleeble simulator to study the effect of FH annealing on the grain and phase structure of a heavily deformed high-Mn TWIP steel at 1000-1200 °C for 2 s soaking time. A remarkable improvement in the mechanical properties was achieved due to grain refinement and controlled hard ferrite phase Recently, Liu et al [19] investigated the impact of flash heating with HR ∼ 300 °C/s on the phase transformations and mechanical performance of Quenching & Partitioning (Q&P) steels.…”

Hot deformation behavior and constitutive modeling of a cost-effective Al8Cr12Mn25Ni20Fe35 high-entropy alloy

“…Haase et al [19] compared high manganese steel (HMnS) to other HEAs containing high percentages of Mn. Reuniting the modern strengthening concept to activate strengthening mechanisms at an appropriate time, the high manganese content in HMnS improved plasticity owing to its low stacking fault energy (SFE) [20]. The mechanical properties can be enhanced by activating either martensitic transformations or mechanical twinning to achieve higher strength and larger elongation, facilitating low-temperature industrial applications such as in the automotive sector.…”

A multiscale indentation-based technique to correlate acoustic emission with deformation mechanisms in complex alloys

“…These AE studies include detection of dislocation nucleation and glide [7][8][9][10], twin nucleation and growth [11,12], and martensitic transformation (MT) [13][14][15], which can be thermally-or stress-activated. The detection of MT is of particular technological relevance, as this mechanism underpins the mechanical performance of several engineering alloys including Mn steels [16,17], austenitic stainless steels [18], and metastable high entropy alloys [19,20]. Van Bohemen et al [13,21,22] used AE to study the evolution of thermally-induced martensite and determined the martensite start temperature during continuous cooling of low alloy steels from high temperature.…”
