In a vast experimental campaign undertaken to investigate the fatigue damage mechanisms operating in this alloy, subject to complex loading conditions, it was shown that two different coexisting fatigue damage mechanisms occur in this materials, depending on the presence of different microstructural heterogeneities i. A defect was represented by a semi-spherical void situated at a specimen surface subjected to periodic loading.
This class of superalloy is characterized by having excellent mechanical properties strength, hard-ness etc. Published on Apr 1, in Procedia Engineering. References 38 Citations 34 Cite. Abstract Experimental Kitagawa analysis has been performed on AT6 containing natural and artificial defects.
High cycle fatigue approach based on affected depth and considering the secondary dendrite arming spacing SDAS effect for a defective AT6 alloy. In particular, the AlSi7Cu05Mg03 alloy is investigated. To advance fatigue life prediction algorithms, more comprehensive knowledge of the intensity and distribution of slip within microstructure at the notch root is desired to quantify notch size effects.
It can be used in many areas, such as for watch and jewellery making, in the medical field for surgical aids, endoscopic surgery and orthopedics or in aerospace for the manufacture of mounting parts.
High cycle fatigue damage mechanisms in cast aluminium subject to complex loads. DSG approach is finally implemented in a finite element simulation of a structural component in order to show that such an approach can provide a defect size map.
However, random 2-D sections through pores do not provide good estimates of the defect size without further data analysis. Affected depth approach to determine the fatigue strength of materials containing surface defects.
In both states — as-built and solution heat treated — the parts can be machined, spark-eroded, welded, micro shot-peened, polished, and coated if required.

It is shown that the critical defect size that does not lower the fatigue strength is close to the grain size of the material. What is more, EOS is constantly refining its high-tech materials based on specific customer requirements.
