iii Abstract: High manganese TWIP (TWinning Induced Plasticity) steels are particularly attractive for automotive applications because of their exceptional properties of strength combined with an excellent ductility. However, as austenitic steels, they appear to be sensitive to liquid zinc embrittlement during welding, the liquid zinc arising from the melted coating due to the high temperatures...

During the turning process of metastable austenitic steels, austenite is transformed into hard martensite by plastic deformation at low temperatures. This enables production components, which have both a hardened subsurface zone and ductile core. Cryogenic cooling allows to be during machining, leads shortening chain. However, effects such as wear can make it challenging adjust properties turni...

Metastable austenitic stainless steels (MASS) are widely used in various industrial applications due to their exceptional compromise between mechanical properties and corrosion resistance. However, the of these materials can be further enhanced by surface treatments. This paper reviews treatment methodologies improve MASS, with particular attention laser The effects treatments on microstructure...

Abstract The processability of medium Mn-containing steels (MMnS) with 4–10% Mn is discussed in light their continuous casting behavior. Precipitation, phase transformation, extension, or shift solidification intervals induced by various alloying concepts are decisive controlling the hot ductility. It turns out that formation complex AlN and MnS precipitates as well ??ferrite deteriorates high ...

In recent years, TRIP/TWIP steels have been the focus of great attention thanks due to their excellent tensile strength-ductility combination. The compression tests were performed at different temperatures from 25 to1000°C to study the mechanical behavior of advanced austenitic steel with 21% manganese plus bearing Ti. The results indicated that the plastic deformation is controlled by deformat...

in the present study, the corrosion behavior of aisi 347 austenitic stainless steel to astm a335 low alloysteel dissimilar joint was investigated. for this purpose, two filler metals, er309l and ernicr-3, were selected to be used during the gas tungsten arc welding process. to investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solut...
