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 ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design
steel research international, EarlyView.Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Stability of retained austenite in TRIP-assisted
, 2004 A theory is developed for the quantitative representation of the strain induced transformation of retained austenite in low alloy, TRIP-assisted steels of the type developed for the automobile industry. It is possible, therefore, to calculate the fraction of austenite as a function of the plastic strain, chemical composition, deformation temperature ...

steel research international, EarlyView.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

steel research international, EarlyView.The studied X65MoCrWV3‐2 press hardening tool steel, produced via laser‐based direct energy deposition DED‐LB/M, exhibits a 15‐20% lower thermal conductivity than its conventionally produced equivalent when heat‐treated to operational hardness. The microstructural evolution during the employed direct tempering leads to anisotropic thermal transport, as

The Mossbauer spectroscopy studies of retained austenite
, 2007 Purpose: of this paper: This paper completes the knowledge concerning the mechanisms of destabilization and properties of retained austenite. Investigations were performed on 120MnCrMoV8-6-4-2 steel, which was designed in 1998, in Phase Transformations Research Group of Department of Physical and Powder Metallurgy at the Faculty of Metals Engineering

steel research international, EarlyView.The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

The design of an Fe-12Mn-O.2Ti alloy steel for low temperature use [PDF]
An investigation was made to improve the low temperature mechanical properties of Fe-8 approximately 12% Mn-O 2Ti alloy steels. A two-phase(alpha + gamma) tempering in combination with cold working or hot working was identified as an effective treatment.
