5th International High Manganese Steel Conference - HMNS 2022

In the past decade, many efforts have been paid to improve the product of strength and elongation of medium Mn steels (containing 3~12 wt% Mn). Due to smelting difficulty and cost reasons, the application of higher Mn steels is limited. In this paper, an Nb-microalloyed 4Mn medium Mn steel, Fe-4Mn-2Al-0.2C-0.02Nb (0.02Nb steel), was prepared and short-time annealing toughening was achieved....

The goal of the research carried out using static and dynamic FWM and HPB methods was to obtain material characteristics, and most of all a detailed analysis of changes occurring in the high manganese steel microstructure in a broad range of deformation rates and deformation magnitudes. The research confirmed that deformation of steel in the static range occurs mainly via dislocation glide. It...

The influence of La additions on the microstructure and high temperature oxidation of austenitic steels Fe-20-25Mn-10-12Al-1C (wt.-%) has been investigated. Three different alloys were produced from commercially pure metals by an arc furnace with a water-cooled copper hearth and a non-consumable tungsten electrode. The melting was performed in an Ar atmosphere (99.98% purity) additionally...
