Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

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, EarlyView.
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.

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

Study on the Amplification Factor of Ice‐Shedding Jump Height of Transmission Lines Under Ice–Wind Coupling

High Voltage, EarlyView.
ABSTRACT Ice accumulation on transmission lines poses a persistent threat to grid stability, yet precise technical guidance for the dynamic response during ice shedding under wind loads remains insufficient. In response to this issue, this study uses C++ to create a calculation program and obtains aerodynamic coefficients of ice‐covered conductors with

A Systematic Review on the Presentation and Management of Segmental Testicular Infarction

Andrology, EarlyView.
ABSTRACT Background Segmental testicular infarction (STI) is a rare and likely underdiagnosed cause of acute scrotal pain. Its clinical and imaging presentation often mimics testicular torsion or malignancy, frequently leading to unnecessary surgical intervention.
