Specimen design for gigacycle fatigue testing of structural steel welded joints
Procedia Structural IntegrityStructures and components across a range of industries exhibit service lives above 10 7 cycles, but there is limited fatigue data in this domain. Conducting fatigue tests in the gigacycle regime is only feasible by using ultrasonic fatigue testing ...

Damage evolution in the AlMg6 alloy during high and very high cycle fatigue
Fracture and Structural Integrity, 2019 Paper presents the “in situ” method for determining of irreversible fatigue damage accumulation, based on the analysis of nonlinear manifestations of the feedback signal in a closed system of an ultrasonic fatigue system.

Crack path in aeronautical titanium alloy under ultrasonic torsion loading [PDF]
Fracture and Structural Integrity, 2016 This paper discusses features of fatigue crack initiation and growth in aeronautical VT3-1 titanium alloy under pure torsion loading in gigacycle regime. Two materials: extruded and forged VT3-1 titanium alloys were studied.

Advanced Engineering Materials, EarlyView.Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Ultrasonic fatigue testing device under biaxial bending [PDF]
Fracture and Structural Integrity, 2016 A new fatigue testing device has been developed to test specimens under biaxial loading at 20 kHz. A flat smooth specimen with a disc geometry is placed on a torus frame and cyclically loaded at the center of its upper face.

DEVELOPMENT OF CYCLIC SLIP BANDS IN UFG COPPER IN GIGACYCLE FATIGUE
Acta Metallurgica Slovaca, 2013 Ultrafine-grained (UFG) copper studied in this paper was produced by equal channel angular pressing (ECAP) method and tested in gigacycle fatigue region. In contrary to conventional grain size copper, the appearance of cyclic slip bands is quite rare and

Influence of defects on the very high cycle fatigue behaviour of forged aeronautic titanium alloy
MATEC Web of Conferences, 2014 This paper is focused on fatigue failure of forged aeronautic titanium alloy Ti-6Al-4Mo under VHCF loading. Continuous fatigue tests were carried out in gigacycle fatigue regime (up to on 1010 cycles) on specimens machined from real aircraft compressor ...
