Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

Analysis of phase transformation in high strength low alloyed steels

Metalurgija, 2017
The effect of low-alloy additions on phase transformation of high strength low alloyed steels is reported. Various as-quenched materials with microstructures consisting of low carbon (granular) bainitic, mixed bainitic/martensitic and fully martensitic ...

Variational modeling of martensitic phase transformations

, 2016
Mechanical material models may be derived and developed via various ways. One possibility roots in the energetic description of the physical processes which evolve in materials under loads. The goal of the present thesis is the presentation of the benefits of such variational modeling approaches through application to shape memory alloys which exhibit ...

Extraction replica method from thinned transmission electron microscopy samples without floating off carbon films: A case study on reduced activation steel

Journal of Microscopy, EarlyView.
Abstract A recipe for producing carbon extraction replicas from twin‐jet electropolished disks is described. This technique allows tracking the analysed region with respect to the bulk sample. An example use of the method as applied to a reduced activation ferritic martensitic (RAFM) steel, ‘UK‐RAFM’, is reported.

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

A Proof of Principle for the Phase‐Dependent Electrocatalytic Activity of NiTi Shape Memory Alloys for the Oxygen Evolution Reaction

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
We compare martensitic (Ni50Ti50) and austenitic (Ni51.2Ti48.8) NiTi shape memory alloys at room temperature as oxygen evolution reaction (OER) anodes, demonstrating that phase‐dependent microstructure governs electronic conductivity, surface roughness, and wettability.
