The role of α′-martensite on the variation of compressive residual stress in a gradient nanostructured austenitic stainless steel

Materials & Design
The strain-induced martensitic transformation (α′-martensite) and residual stress (RS) introduction in the gradient nanostructured (GNS) austenitic stainless steel have been extensively reported in the last three decades, however, their correlation is ...

From section to structure: Assessing the impact of localized corrosion on reinforced concrete beams

Structural Concrete, EarlyView.
Abstract The structural behavior of reinforced concrete (RC) elements affected by localized corrosion represents a major challenge for ensuring structural safety and for the proper design of strengthening interventions. The effects of localized corrosion on the flexural behavior of RC beams remain a topic of debate within the scientific community.

Formation of bainite below martensite start temperature in quenching low carbon steel

St. Petersburg Polytechnical University Journal: Physics and Mathematics
According to the phase transformation kinetics that we recorded by dilatometry in rapid cooling of low carbon steel, some amount of isothermal bainite appeared in the middle of martensitic temperature range.

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

Journal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

Meteoritics &Planetary Science, EarlyView.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

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%.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.
