High-manganese Hadfield cast steel is commonly used for machine components operating under dynamic load conditions. The high fracture toughness and abrasive wear resistance of this are the result an austenitic structure, which—while being ductile—at same time tends to surface harden effect cold work. Absence loads (e.g., in case sand abrasion) causes rapid premature parts. To improve high-manga...

*Correspondence: Demircan Canadinc, Rumeli Feneri Yolu, Sariyer, Istanbul, Turkey e-mail: [email protected] A multi-scale modeling approach was applied to predict the impact response of a strain rate sensitive high-manganese austenitic steel. The roles of texture, geometry, and strain rate sensitivity were successfully taken into account all at once by coupling crystal plasticity and finite e...

Paper presents the research of austenitic steel AISI 304after ion nitriding at 400◦C and at t =4h, for the two different variants of samples distribution in the working plasma reactive chamber tube. In order to assess the effectiveness of ion nitriding variants emission spectroscopy – GDOES, surface hardness tests, microstructure research (LM) of nitrided layers were made. It has been found tha...

Using X-ray diffraction, scanning and transmission electron microscopy, the microstructure of a new low-activation chromium-manganese austenitic steel with high content manganese strong carbide-forming elements is studied. Its structure, dislocation character particle composition are detailed. The processes taking place in under cold-rolling deformation described. It shown that mechanical prope...

in this paper, the correlation between the surface rumpling and cracking phenomena with twinning mechanism during plastic deformation of hadfield steel has been investigated. the effect of stacking fault energy and the amount of strain are evaluated. the experimental samples with specific amounts of carbon, manganese and aluminum resulting in different stacking fault energies, were produced usi...

Interest in eco-friendly energy is continuously increasing worldwide. LNG a good source with use. has temperature of -165 ℃ and requires low-temperature toughness for the tank material. High manganese austenitic steel similar mechanical properties to cryogenic materials LNG, as listed IGC IGF codes. easily satisfies requirement at exhibits superior performance terms yield strength, tensile elon...
