FATIGUE BEHAVIOR OF TWO-PHASE TITANIUM ALLOY IN VHCF REGIME

, 2017
This paper is focused on fatigue crack initiation and early growth in two-phase titanium alloy VT3-1 (similar to Ti-6Al-4V) under VHCF loads. The material was produced by two different processes: forging and extrusion. Each kind of material was investigated under three different loading types (push-pull, pull-pull and fully reversed torsion).

Carbon‐Driven Enhancement in Zinc Hexacyanoferrate Composites: A Ball‐Milling Approach for High‐Performance Zn‐Ion Batteries

ChemElectroChem, Volume 12, Issue 20, October 16, 2025.
Structural modification of ZnHCF cathodes via ball‐milling and carbon addition significantly enhances the electrochemical performance of aqueous zinc‐ion batteries, achieving capacities close to 100 mAh g−1. The synergistic effect of carbon with ZnHCF preserves the crystalline structure and facilitates phase transitions, greatly improving the cathode's

Influences on the Fatigue Strength of Laser‐Welded High‐Purity Copper Connections

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 10, Page 4148-4160, October 2025.
ABSTRACT Due to their excellent conducting properties, components made of high‐purity copper are increasingly being used in the field of electrified applications. In particular for components with welded joints made of high‐purity copper, there is still no computational basis for evaluating the fatigue strength of these joints.

Effect of long-period stacking ordered structure on very high cycle fatigue properties of Mg-Gd-Y-Zn-Zr alloys

Journal of Magnesium and Alloys, 2023
Magnesium alloys with a long-period stacking ordered (LPSO) structure usually possess excellent static strength, but their fatigue behaviors are poorly understood. This work presents the effect of the LPSO structure on the crack behaviors of Mg alloys in

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.
ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with

Effect of Stress Ratio on Very High Cycle Fatigue Properties of PM‐HIPed Inconel 625

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 8, Page 3593-3610, August 2025.
ABSTRACT This study investigated the impact of stress ratio on the fatigue performance and fatigue crack initiation characteristics of PM‐HIPed Inconel 625 in the very high cycle regimes. Ultrasonic fatigue tests, operating at a frequency of 20 kHz, were conducted on PM‐HIPed Inconel 625 samples under stress ratios of R = −1 and 0.1 up to the ultimate ...

Fatigue Testing of Carbon Fibre Reinforced Polymers under VHCF Loading

Procedia Materials Science, 2013
AbstractThe rapidly developing market for high strength and high stiffness carbon fibre reinforced polymers (CFRP) among others demands for reliable damage evaluation methods at very high cycle fatigue loading (VHCF). Due to the anisotropic nature of continuous fibre reinforced composites, fatigue damage is initiated in various failure modes.
