Modelling the microstructure of martensitic steels [PDF]
Computational Materials Science, 2015 A method based on the kinetics of crystal growth has been developed and applied to the computation of three-dimensional microstructure in austenite–martensite steels. The detailed crystallography of the transformation is used to model a realistic martensitic microstructure during the transformation without an external system of stresses.

Influence of Strain Rate on the Strain Hardening Behavior of a Lean Duplex Stainless Steel
MetalMat, EarlyView.The aim of this study was to examine how strain rate influences the compressive strain‐hardening behavior of a lean duplex stainless steel LDX 2101. Microstructural analysis using electron backscatter diffraction (EBSD) revealed a strain‐induced austenite‐to‐martensite transformation.

An evaluation of weld metal nitrogen retention and properties in 316NL austenitic stainless steel
, 2011 A series of tests were conducted using varying levels of nitrogen and helium in a conventional argon shielding gas when welding 316LN austenitic stainless steel. The outcome was that a 15 per cent nitrogen addition to the argon shielding gas had the most

Yielding Behaviour of Martensite in Steel
ISIJ International, 2015 Although martensite is recognised as a very strong phase in carbon steels, its initial yielding commences at low stresses and the tensile stress-strain curve shows a smooth, rounded form. Evidence is presented from x-ray diffraction to show that this behaviour is due to the presence of intra-granular stresses that are residues after the shear ...

Application of Machine Learning in Heat Treatment Process Design of Carburized Steel
Materials Genome Engineering Advances, EarlyView.To accelerate heat treatment design, we constructed a closed‐loop machine learning strategy involving multi‐source datasets and feature screening. The optimized model accurately predicts hardness and friction coefficients, successfully guiding the process optimization for two typical carburized steels with high experimental consistency.

Effect of δ-ferrite on the H-trapping behavior in the martensitic stainless steel
Journal of Materials Research and Technologyδ-ferrite usually plays an important role in the mechanical properties of martensitic stainless steel. However, there are few studies on the effect of δ-ferrite on hydrogen embrittlement (HE) in martensitic steel.

steel research international, EarlyView.On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.
