Fatigue performance in both traditional and additively manufactured materials is severely
affected by the presence of defects, which deserve special attention to ensure the in-service …

Global warming and extreme climate problems caused by the intensive exploitation of fossil
fuels have become increasingly serious. With the urgent global demand for clean energy …

Fatigue short crack growth governed by the crack-tip plasticity dominates the fatigue life and
strength of metallic materials or structural components. Here, for the first time, we discover a …

In this study, the high cycle and very high cycle fatigue behavior of the GH4169 superalloy
was investigated. The results of the fatigue tests demonstrated that failures in the high cycle …

Rotating bending fatigue tests, together with microstructural characterization, have been
performed on the high nitrogen martensite bearing steel Cronidur30. The results show that …

The objective of this study was to investigate the cyclic deformation mechanisms at the
microstructural level and their correlation with the initiation and early propagation of small …

In this study, the relationship between fatigue life and the feature parameters of fatigue
fracture surfaces was statistically analyzed to successfully develop a new fatigue life …

High and very high cycle fatigue (HCF and VHCF) behaviours and failure mechanism of
Inconel 718 were investigated via ultrasonic fatigue tests and microscopic characterization …

We emphasized the competing and synergistic effects of microstructure and non-metallic
inclusion on subsurface fatigue crack initiation behaviors of bainitic/martensitic rail steels …

Due to their distinct physical, chemical, and mechanical features, high-entropy alloys have
significantly broadened the possibilities of designing metal materials, and are anticipated to …
