Crack initiation mechanisms in the very high cycle fatigue (VHCF) regime of nickel-based
single-crystal (SX) superalloys have been investigated at high temperature (1000° C) and …

Over the last decade, it has been shown for a number of metals that failure occurs even
beyond the classical fatigue limit. High frequency testing techniques make it possible to …

The coupling effects of microstructure and macro-scale defects are significant for the fatigue
properties of metallic materials. However, this correlation is still vague for additively …

This study aims to investigate the effects of duplex surface treatment consisting of plasma
nitriding and DLC coating on the fatigue properties of Ti6A4V alloy. For this investigation …

Crack initiation mechanisms under two stress ratios (R=− 1 and 0.5) and up to very-high-
cycle fatigue (VHCF) regime of a selective laser melted (SLMed) Ti-6Al-4V were …

This paper presents the results on the microstructure and mechanical properties of damage
tolerance TC4-DT titanium alloy after different heat treatments. The influence of volume …

High frequency fatigue tests were carried out with a 20 kHz ultrasonic testing facility to
investigate the cyclic deformation behavior of Ti6Al4V in the Very High Cycle Fatigue …

The behavior of crack initiation and early growth in high-cycle fatigue (HCF) and very-high-
cycle fatigue (VHCF) regimes for a TC4 titanium alloy with equiaxed microstructure was …

The propagation of an internal fatigue crack in Ti–6Al–4V was non-destructively observed by
synchrotron radiation μCT imaging to clarify the crack growth rate in very high cycle fatigue …

Accelerated fatigue tests with Ti6Al4V were carried out using a 20 kHz ultrasonic testing
