A method of collecting composition data and examining structural features of pearlite lamellae and the parent austenite at the growth interface in a 13wt. % manganese steel has been demonstrated with the use of Scanning Transmission Electron Microscopy (STEM). The combination of composition data and the structural features observed at the growth interface show that available theories of pearlit...

The effects of gas nitriding temperature on the cross section morphology, element nitrogen distribution, and surface layer compositions of a cold rolled and pre-strained high manganese austenitic TWIP steel 25Mn-3Cr-3Al-0.3C-0.01N and the corresponding anti-corrosion ability have been studied. The results show that, depending on nitriding temperature, the distribution of element nitrogen and ma...

in this study, the effect of tensile test temperature (148 to 673 k) on the microstructural evolutions and the mechanicalproperties of high manganese twinning induced plasticity (twip) steel with the chemical composition of fe-31mn-3al-3si (wt. %) was investigated. xrd, sem and tem were used to study the microstructural evolutions.stacking fault energy (sfe) of the alloy was also calculated by ...

Austenitic carbon steels that exhibit excellent mechanical properties due to the twinning-induced plasticity effect have been studied extensively. On the other hand, austenitic stainless steels usually achieve good strength and ductility via transformation-induced plasticity. However, relying on martensite transformation for strength may cause problems such as delayed cracking. Therefore, the t...

*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...

This work aims to describe the interfacial interaction at interface between refractory material and high-manganese (XT 720) structural (11 523) steel using a wetting test up 1600 °C. The contact angles were determined through sessile drop method, results put into context degradation testing characterization of by Energy Dispersive X-Ray (EDX), Diffraction (XRD) analyses, Scanning Electron Micro...

A series of 18 Ni (300 grade) maraging steels of overall commercial purity but containing also deliberate impurity additions of sulphur, phosphorus, carbon, chromium and silicon + manganese has been studied. The fracture toughness and stress-corrosion resistance (determined using planestrain fatigue-precracked specimens tested in 3. 5% sodium chloride solution) of these steels have been compare...

A titanium–iron intermetallic with minor addition of manganese (TiFe0.7Mn0.3) was processed by severe plastic deformation through high-pressure sliding (HPS). rectangular strip sample embedded in stainless steel and strained under a pressure 4 GPa at room temperature. The hydrogen storage kinetics activation the HPS-processed were significantly enhanced comparison as-received ingot without HPS ...
