“…7b), revealing the dislocation hardening mechanism for moderate deformation. The results are quite different from those in the other reports, such as twin hardening, 15,16 dynamic strain induced aging hardening. 17 In addition, comparing to the condition of the impact wear, the explosion hardening of the high manganese steel results in lower surface hardness and thicker hardening layer.…”

In the present paper the effects of explosion hardening on the microstructure and the mechanical properties as well as the lifetime of Hadfield steel (high manganese steel) crossing have been studied. The optimum explosion hardening technology of the high manganese steel crossing was proposed. That is twice explosion by using cyclonite explosive in thickness of 3 mm. The new technology emphasises the formation of a 25 mm deep hardened layer with surface hardness of 370 HB. Upon the explosion impact, the deformation mechanism of the material is found to follow in situ plastic deformation. The explosion hardening mechanisms of the high manganese steel crossing are dislocation and nanoscale deformation twin hardenings in the surface layer which is subjected to large deformation, and dislocation hardening in the subsurface layer which is subjected to small deformation. The explosion hardening enhances the mechanical properties of the material, included the deformation resistance, wear resistance and fatigue resistance, therefore, the lifetime of the high manganese steel crossing can be increased by ∼35% through the explosion hardening treatment.

“…The tensile strength and ductility reach a maximum at about 1.2%C and then decrease steadily as the carbon content is increased. The same mechanical properties however, increase rapidly with increasing Mn content up to 12% and tend to level off [1,2].…”

“…But it has been shown that the austenitic phase in Hadfield steel is stable during plastic deformation at all temperatures [2,3]. Strain induced transformation occurs only because of decarburization or local segregation of manganese leading to unstable austenite composition.…”

ABSTRACT-In this study, the original Hadfield steel (1.2%C and 12%Mn) is investigated under uniaxial tensile test conditions in order to evaluate the mechanical behaviour at different strain rates and temperatures. The constitutive equation of Hadfield steel is determined as a function of strain, strain rate and temperature. In an attempt to explain the mechanism of rapid strain hardening of this steel, microstructural study is also performed and the findings are related to deformation behaviour with the intent of clarifying one of the major problems of Hadfield steel.

“…The effect of molybdenum on the X120Mn12 steel is documented by Röhrig 6 and steels with additions of Ti, Al and N were tested 7 . Further research on steels with Mn content up to 19 % and C content up to 1.78 % can be found in several papers 2,[8][9][10][11] .…”

three high-manganese austenitic steels (X120Mn12, X80Mn16 and X60Mn22) and a standard Cr-Ni-austenitic steel X5CrNi18-10 regarding some selected aspects of their processing behavior. The hot deformation and dynamic recrystallization behavior between deformation steps as well as the static recrystallization from a cold rolled state were investigated. To evaluate mechanical properties and cold forming behavior, characteristic values were determined by means of Erichsen testing. In addition, structural investigations were conducted by XRD and optical microscopy as well as scanning electron microscopy. Austenitic highmanganese steels require lower deformation forces than austenitic Cr-Ni steels and exhibit a significantly more rapid dynamic recrystallization. Thereby the X60Mn22 steel grade showed significantly higher yield strength than the other high-manganese steels. Static recrystallization takes place after short holding durations at temperatures lower than required for solution treatment. All austenitic high-Mn steels showed a better formability but higher stretch-forming forces during cold forming compared to the austenitic Cr-Ni-steel. Vergleich von austenitischen Hoch-Mn-Stählen mit unterschiedlichen Mn-und C-Gehalten hinsichtlich ihrer VerarbeitungseigenschaftenDiese Arbeit beschäftigt sich mit der Zusammenfassung: Charakterisierung dreier austenitischer Hoch-Mn-Stähle (X120Mn12, X80Mn16 und X60Mn22) im Vergleich zu einem konventionellen austenitischen Cr-Ni-Stahl X5CrNi18-10 bezüglich ausgewählter Verarbeitungseigenschaften. Das Warmumformverhalten und die dynamische Rekristallisation zwischen den Umformschritten sowie die statische Rekristallisation des kaltgewalzten Materials wurden untersucht. Charakteristische Werte für die mechanischen Eigenschaften und das Kaltumformverhalten wurden durch Erichsen-Tests ermittelt. Strukturuntersuchungen wurden mit Hilfe von Röntgendiffraktometrie, Licht-und Rasterelektronenmikroskopie durchgeführt. Für die Bearbeitung von austenitischen Hoch-Mn-Stählen ist eine geringere Umformkraft notwendig als für den austenitischen Cr-Ni-Stahl, außerdem zeigt sich eine wesentlich schnellere dynamische Rekristallisation. Der Stahl X60Mn22 zeigte eine signifikant höhere Fließspannung als die anderen Hoch-Mn-Stähle. Die statische Rekristallisation setzt schon nach geringen Haltezeiten ein und läuft schon bei Temperaturen unter der Lösungsglühtemperatur ab. Bei der Kaltverformung zeigten alle austenitischen Hoch-Mn-Stähle eine bessere Umformbarkeit, aber höhere Umformkräfte, im Vergleich zum Cr-Ni-Stahl.
