VHCF of spray formed hypereutectic aluminium silicon alloy [PDF]
MATEC Web of Conferences, 2014 Ultrasonic fatigue experiments in the very high cycle fatigue (VHCF) regime are performed with spray-formed hypereutectic aluminium silicon alloy DISPAL® S232-T6x. DISPAL exhibits excellent mechanical properties with low weight and can achieve higher stiffness, greater high temperature strength, excellent wear resistance and a reduced coefficient of ...

VHCF Response up to 109 Cycles of SLM AlSi10Mg Specimens Built in a Vertical Direction
Applied Sciences, 2019 It is well-known that many manufacturing parameters affect the quasi-static and the fatigue response of additive manufacturing (AM) parts. In particular, due to the layer-by-layer production, the load orientation, with respect to the building direction ...

Computational micromechanics of fatigue of microstructures in the HCF–VHCF regimes [PDF]
International Journal of Fatigue, 2016 Abstract Advances in higher resolution experimental techniques have shown that metallic materials can develop fatigue cracks under cyclic loading levels significantly below the yield stress. Indeed, the traditional notion of a fatigue limit can be recast in terms of limits associated with nucleation and arrest of fatigue cracks at the microstructural

Influence of artificial seawater on the VHCF behavior of different steels
Fatigue & Fracture of Engineering Materials & Structures, 2022 AbstractThe fatigue properties of a high‐strength steel, a structural steel, and a duplex stainless steel in artificial seawater were investigated. Consequently, a test chamber for the existing ultrasonic test stand was implemented. The experiments were performed with smooth specimens at a loading with R = −1 up to 2 · 109 cycles.

Crack propagation mechanism and life prediction for very-high-cycle fatigue of a structural steel in different environmental medias [PDF]
Fracture and Structural Integrity, 2013 The influence of environmental medias on crack propagation of a structural steel at high and very-high-cycle fatigue (VHCF) regimes is investigated based on the fatigue tests performed in air, water and 3.5% NaCl aqueous solution.
