Effect of carbide characteristics on abrasive wear behavior during knife honing: A comparative study of martensitic stainless steel and spring steel

Journal of Materials Research and Technology
The resharpenability of knife steels is crucial for extending kitchen knife service life, yet the underlying mechanisms governing edge reconstruction during sharpening remain poorly understood.

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 ...

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

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.

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

steel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.

Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.
