Abstract The ternary-based Fe-24Mn-3Cr alloy has superior mechanical properties based on an attractive combination of high strength and ductility, with long-term environmental stability in highly corrosive environments compared to conventional ferrit

To expand the industrial applicability of strong and ductile high Mn-Low Cr steel, a deeper understanding and mechanistic interpretation of long-term corrosion behavior under harsher environmental conditions are needed. From this perspective, the lon

The near-threshold fatigue crack propagation behavior of high manganese steels, including 24Mn4Cr, 22Mn3Cr, 20Mn, 18Mn and 12Mn steels, were examined at 298, 173 and 113 K, and the results were compared to those of widely used cryogenic alloys, inclu

The fatigue crack propagation (FCP) tests were conducted on Fe24Mn steel in the region of base metal (BM), weld metal (WM) and fusion line (FL) at 298 and 110 K. The FCP rates of Fe24Mn specimens in the region of BM, WM and FL were greatly decreased,

Microstructural evolution of an Fe-22 pct Mn-0.4 pct C twinning-induced plasticity (TWIP) steel during high strain rate deformation has been investigated. When subjected to low strain rate deformation, the steel shows the typical TWIP phenomenon. On

In the current study, the S–N fatigue and the fatigue crack propagation (FCP) behaviors of high manganese austenitic steels, including Fe24Mn and Fe22Mn, were studied, and the results were compared with STS304 (Fe-1Si-2Mn-20Cr-10Ni). The S–N fati

It is usually believed that formation of gas and shrinkage porosity has different dependencies on the process conditions, and consequently, the gas and shrinkage pores are usually regarded as independent microstructural features. In this contribution

The spatial arrangement and heterogeneity of microstructural features, in particular, porosity in the cast microstructures, adversely affect the mechanical properties, and consequently lead to significant variability in the properties. Clearly, succe
