Abstract. High-Mn steels have great plasticity when subjected to deformation due TWIP or TRIP effects. This work evaluated the microstructural evolution, formation of -Martensite phase taking into account hot rolling 80-60% and solution annealing. Afterwards, microstructures were analyzed by SEM. Volume fraction Austenite phases measured EBSD technique. The steel obtained low energy levels sta...

High-manganese twinning-induced plasticity (TWIP) steels exhibit high strain hardening, tensile strength, and ductility, which make them attractive for structural applications. At low rates, TWIP are prone to hydrogen embrittlement (HE). Here though, we study the hardening strengthening resulting from electrochemical hydrogen-charging of a surface layer Fe-26.9Mn-0.28C (wt.%) steel. We observed...

Abstract High manganese steels are well used for their excellent hardening properties. In this study, we investigate the mechanical responses of high steel in a compressed condition. During compression deformation, twin crystal is first generated inside some grains with orientation advantage, and then all twinned. Selective twinning on leads to formation textural structures. When plastic deform...

Overexposure to welding fume constituents, particularly manganese, is of concern in the construction industry due to the prevalence of welding and the scarcity of engineering controls. The control effectiveness of a commercially available portable local exhaust ventilation (LEV) unit was assessed. It consisted of a portable vacuum and a small bell-shaped hood connected by a flexible 2 inch (50....

Welders are at risk of being exposed to high concentrations of welding fumes and developing pneumoconiosis or other welding-fume exposure-related diseases. Among such diseases, manganism resulting from welding-fume exposure remains a controversial issue, as although the movement of manganese into specific brain regions has been established, the similar movement of manganese presented with other...

AISI 430 ferritic stainless steel is a promising candidate for utilising as interconnects of solid oxide fuel cells due to its cost effectiveness and durability. Many methods applying coating on substrates have been developed in order decrease the degradation oxidation rate chromium volatile problems. Manganese-cobalt spinel exhibits high conductivity, thermal expansion compatible with steels, ...
