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

steel research international, EarlyView.
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.

Influence of Laser Powder‐Based Directed Energy Deposition and Heat Treatment on the Thermal Conductivity of Cold‐Work Tool Steel X65MoCrWV3‐2

steel research international, EarlyView.
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

Record‐breaking May heat in the UK: contrasting the extreme temperatures of 2024 and 1944 using climate attribution

Weather, EarlyView.
This study quantifies the likelihood of May temperature extremes in present, natural (climatology based on pre‐industrial forcings) and future climates. The attribution applies in the context of a May heatwave comparable to the record‐breaking 1944 event and the persistent record‐breaking monthly‐mean temperature from 2024.

Extreme rainfall in Madeira: the June 2023 weather event

Weather, EarlyView.
This study investigates the meteorological conditions behind the extreme precipitation event on 6 June 2023 over Madeira Island, Portugal. The event set a national daily record of 497.5mm and was unusual for occurring in early summer, as most extremes in the region occur in winter.

Investigation of Dielectric and Thermal Properties of Mineral Oil‐Based Fe3O4‐Coated SiO2 Core‐Shell Nanofluids

High Voltage, EarlyView.
ABSTRACT This study investigates the dielectric and thermal properties of transformer oil‐based nanofluids incorporating Fe3O4‐coated SiO2 core–shell nanoparticles as nanofillers. The nanoparticles were synthesised with varying shell thicknesses, and two samples underwent surface treatment.

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Civility, honour and male aggression in early modern English jestbooks

Gender &History, EarlyView.
Abstract This article discusses the comical representation of inter‐male violence within early modern English jestbooks. It is based on a rigorous survey of the genre, picking out common themes and anecdotes, as well as discussing their reception and sociable functions. Previous scholarship has focused on patriarchs, subversive youths and impoliteness.
