In this work, the effects of loading condition and corrosion solution on the corrosion fatigue behavior of smooth steel wire were discussed. The results of polarization curves and weight loss curves showed that the corrosion of steel wire in acid solution was more severe than that in neutral and alkaline solutions. With the extension of immersion time in acid solution, the cathodic reaction of ...

Abstract S500MC steel is a grade of high-strength low-alloy (HSLA) which widely used in the automotive industry and for agricultural machinery equipment. Considering properties this alloy, selection welding process parameters becomes essential to ensure that HSLA assemblies meet specific service requirements. In work, mechanical metallurgical produced by autogenous laser beam (LBW) automatic ga...

The objective of this study was to evaluate the influence of microstructure on the susceptibility to high-cycle fatigue (HCF) failure in Ti–6Al–4V following foreign-object damage (FOD), specifically by comparing a fine-grained bi-modal microstructure with a coarse grained lamellar microstructure. FOD was simulated by high-velocity impacts of steel spheres on a flat surface. This caused a marked...

The effects of environment (in air and 3.5 wt% NaCl solution) artificially-induced surface scratches are investigated on the fatigue properties railway EA4T (also called 25CrMo4) alloy steel. This steel is found to be markedly sensitive chloride-containing environment, with cracking at stresses two thirds in-air limit (+/?326 MPa) under rotating bending (Wöhler) tests. scratched specimens show ...
