Study on the stability of retained austenite in marine steel
Metalurgija, 2020 The residual austenite stability in marine steel was studied by different heat treatment processes. After heat-treatment process 1 (quenching + tempering) and heat treatment process 2 (quenching + intercritical annealing + tempering), the austenite ...

steel research international, EarlyView.Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

steel research international, EarlyView.This review's second part details the mechanical, corrosion, and electromagnetic behaviors of FSSs. It integrates the foundational microstructure (texture/defects/precipitates) and processing effects from Part I to establish and analyze complex property–property interrelationships critical for high‐performance applications.

steel research international, EarlyView.The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Effect of initial grain size of austenite on hot-deformed structure of Ni-30Fe alloy
, 2019 The microstructural evolutions of Ni-30Fe alloys during hot deformation are investigated. Hot-deformed structures of Ni-30Fe alloys with initial austenite grain sizes of 20 and 140 mum are examined under various compressive strains and deformation ...

steel research international, EarlyView.In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...

steel research international, EarlyView.Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...
