High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2097-2115, June 2026.ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.This study investigates how tramp elements from increased scrap usage influence phase transformations in low‐alloyed steel. Combining dilatometry and microscopy reveal that tramp elements delay transformations, reduce critical cooling rates and increase hardenability.

Retention of ductility in high-strength steels [PDF]
, 1969 To produce high strength alloy steel with retention of ductility, include tempering, cooling and subsequent tempering. Five parameters for optimum results are pretempering temperature, amount of strain, strain rate, temperature during strain, and ...

Anchorage System Contribution to Post‐Tensioned Bridge Collapse
Engineering Reports, Volume 8, Issue 5, May 2026.This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Journal of Materials Research and TechnologyA low carbon steel (0.2 wt% C) was quenched from 1000 °C under atmospheric quenching (APQ) into water, and under high pressure (HPQ) of 5 GPa at 10 °C/s. Both APQ and HPQ lead to lath martensite with twinned substructure, showing a hardness of 450 HV and

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

steel research international, Volume 97, Issue 5, Page 2796-2804, May 2026.The studied X65MoCrWV3‐2 press hardening tool steel, produced via laser‐based direct energy deposition DED‐LB/M, exhibits a 15‐20% lower thermal conductivity than its conventionally produced equivalent when heat‐treated to operational hardness. The microstructural evolution during the employed direct tempering leads to anisotropic thermal transport, as
