A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, Volume 97, Issue 10, Page 5079-5089, October 2026.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, Volume 97, Issue 10, Page 5103-5114, October 2026.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

Influences of Cleanliness, Carbide Size, Hardness, and Residual Stresses on Long‐Life Fatigue Strength and Crack‐Initiation Mechanisms in Carbide‐Rich Cold‐Work Tool Steels Using Normalized S–N Curves and Database‐Driven Validation of Murakami's √Area Model

steel research international, Volume 97, Issue 10, Page 5221-5267, October 2026.
Rotating‐bending fatigue tests on AISI D2 and AISI A11 quantify how cleanliness, carbide structure, hardness, and fabrication‐induced compressive residual stresses govern long‐life fatigue at NG = 107 cycles. Statistical fracture‐surface analysis and extreme‐value √area statistics link crack‐initiators to LLF strength.

The effect of Nb and O on the martensitic transformation in Ti–Nb–O alloys

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1570-1583, October 2026.
Using a newly developed 2D X‐ray diffraction orientation simulation approach to isolate overlapping martensitic reflections, this study demonstrates that niobium controls continuous lattice symmetry evolution, whereas interstitial oxygen induces localized strain fields that nonlinearly govern the structural competition between α″‐martensite and the ...

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

Archaeometry, Volume 68, Issue 5, Page 1139-1151, October 2026.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...
