In recent years, medium manganese steels (MMSs) have garnered increased attention and interest due to their relatively low cost superior combination properties compared other steels. particular, MMSs been recognised as ideal wear-resistant materials employed in the mining industry. However, studies on wear performance a lack of systematic documentation. This review provides an extensive overvie...

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 high manganese steels exhibit outstanding mechanical properties, such as energy absorption, owing to various deformation-mechanisms dislocation slip, twinning-induced plasticity (TWIP) and transformation-induced (TRIP). Here, we show a novel thermomechanical treatment manufacture steel Fe–18Mn-0.3C (wt.-%) with excellent performance by combining these three deformation-mechanisms. Th...

Severe plastic deformation response of a face centered cubic (FCC) twinning induced plasticity (TWIP) high entropy alloy (HEA), Fe40Mn40Co10Cr10, subjected to high-pressure torsion (HPT) is investigated. The so-called TWIP HEA demonstrated an extensive transformation (TRIP) effect even in ½ turn (shear strain, ? = 15) HPT processing, which increased further with increasing the number turns 2 (?...

Twinning induced plasticity steels are austenitic alloys in which mechanical twinning is a prominent deformation mode, and which exhibit exceptional combinations of ductility, work hardening and ultimate strength. The authors develop in the present paper a crystallographic theory to enable the quantitative investigation of the role of mechanical twinning in enhancing the properties of these all...
