Further, such a large microstructure would eliminate any local effect of the boundary conditions on any mechanical field variable around the crack initiation site. The physics of fatigue crack initiation is strongly dependent on the material, crystal Conclusions High cycle fatigue analyses at high R...

This failure mechanism is essentially different from the static tensile failure mode in which the large primary TiB2 particles are the main source of fracture failure. 展开 关键词: Steel matrix composite Fatigue crack initiation Interface strength Eutectic particle cluster ...
In the present study, crack initiation criteria, static failure and tensile mode fatigue behavior for a rail steel are evaluated to assure the railway vehicle's safety. The transverse fissure, which is the most critical damage in the rail, is initiated by the maximum shear stress and its locat...
Fatigue cracks were observed along twin bands. Based on cyclic deformation irreversibility caused by twinning, fatigue damage mechanisms are proposed in terms of surface/near surface crack initiation. 展开 关键词: magnesium alloy ultrasonic fatigue crack initiation deformation twins very high cycle fatigue...
Without post-manufacture HIPing the fatigue life of electron beam melting (EBM) additively manufactured parts is currently dominated by the presence of porosity, exhibiting large amounts of scatter. Here we have shown that the size and location of these defects is crucial in determining the fatigue...
Three types of the Al-Si cast aluminum alloys containing different Ti content are prepared with pure aluminum,electrolytic low-titanium aluminum,Al-5% Ti master alloy and so on. The effects of adding Ti method and Ti content on the microstructure,the fatigue crack initiation and growth behavior ...

The aim of this paper was to identify the grain size effect on the small fatigue crack initiation and growth mechanisms of nickel-based superalloy GH4169. Results showed that there was a transition of fatigue crack initiation mechanism between fine-grained material and coarse-grained material. Smal...
