Abstract Metallic cast components inevitably contain defects such as shrinkage cavities which are inherent to the solidification process. Those known significantly alter fatigue life of components. Yet very little is known, quantitatively, on dangerosity internal casting compared surface ones. In this study, specimens containing controlled (shrinkage pores) used foster cracking. situ tests monitored by X ray synchrotron tomography revealed that nucleation and propagation cracks was...
The effect of hammer peening on the fatigue resistance high strength welded joints in structural steel S690 has been investigated. Cyclic four points bending tests have performed butt weld samples, manually and automatically hammered. Microstructural mechanical modifications induced by both methods their subsequent influences life studied using several characterization techniques. It was found that roughness hammered samples is different than for which a lack correct treatment some regions...
Abstract The effect of surface integrity parameters on fatigue life has been investigated. Various surfaces have manufactured with a controlled in order to achieve test and compare the influence each independently (residual stresses, roughness, microstructure). difficulty reproduce same sample had pointed out. It is necessary characterize all samples before testing take it into account procedure. Staircase tests carried out determine average strength at 2.106 cycles for case integrity. First...
