Microstructure Evolution of a Medium Manganese Steel During Thermomechanical Processing [PDF]

open access: yesMetallurgical and Materials Transactions A, 2016
An as-cast Fe-0.2C-10Mn-3Si-3Al medium manganese steel with a ferrite plus austenite duplex microstructure was subjected to hot compression tests at deformation temperatures within two-phase (α + γ) range and various strain rates. The microstructure evolution of the experimental steel during hot deformation was investigated.

Alloying and Processing of Medium Manganese Steels for Forging Applications

open access: yesBHM Berg- und Hüttenmännische Monatshefte, 2022
AbstractThe processability of medium Mn-containing steels (MMnS) with 4–10% Mn is discussed in light of their continuous casting behavior. Precipitation, phase transformation, extension, or shift of solidification intervals induced by various alloying concepts are decisive in controlling the hot ductility. It turns out that the formation of complex AlN

Design of Fully Austenitic Medium Manganese Steels

open access: yesIOP Conference Series: Materials Science and Engineering, 2018
Due to their higher ferrite potential compared to high Mn twinning-induced plasticity (TWIP) steels, medium Mn steels usually exhibit austenitic-ferritic microstructures, which makes them suitable for third-generation advanced high-strength steel applications.
