Aluminum alloysCastingFatigueForgingMetallurgyThe fundamental relationship between semi-solid processing and microstructure and their effect on the flow characteristics of semi-solid metals have been studied for several years. However, how the process related microstructure influences fatigue properties has not...

Aluminum alloy A357 castings are commonly treated to the T6 temper prior to service. Because of this solution heat treatment and artificial aging sequence, the mechanical properties are enhanced. The purposes of this research are to study the kinetics of the solution heat treatment and to relate ...

CRYSTALLOGRAPHYFRACTURE mechanicsFATIGUE lifeELECTRON diffractionCRYSTAL grain boundariesGRAIN sizeThe high-cycle fatigue, small crack propagation behavior of an A357-T6 cast aluminum alloy is investigated. Laboratory X-ray micro-computed tomography $$(\\mu {\\text {CT}})$$ is used to assist in ...
This work aims to quantify the effect of natural shrinkages on the fatigue limit of A357-T6 cast aluminum alloy. The main objective is to characterize the fatigue strength of the alloy following the ASTM X-Ray standard defect identification, by correlating a different ASTM indication to a ...
Solid state sintering of cast aluminum powders by resistance heating sintering (RHS), also known as spark plasma sintering or field-assisted sintering technique, creates a very fine microstructure in the bulk material. This leads to high performance material properties with an impro...
Influence of surface and internal casting defects on the fatigue behaviour of A357-T6 cast aluminum alloy. International Journal of Fatigue, 2016, 82: 361-370Serrano-Munoz I, Buffiere J Y, Verdu C, et al. Influence of surface and internal casting defects on the fatigue behaviour of A357-...
fatigue tests have been performed on structural components casted in A357-T6 aluminum alloy. A non-local fatigue criterion based on the stress gradient has been used in order to simulate the Whler diagram of the components. The criterion is accurate and shows that the stress gradient at the ...
