In this article the results of a recent study designed to improve their understanding of the cyclic fatigue and fracture characteristics of a spray atomized and deposited hypereutectic aluminum-silicon alloy are presented. Specimens of the alloy were cyclically deformed to failure at ambient temperature under fully reversed total strain amplitude controlled tension-compression loading. The alloy exhibited low cyclic plasticity and fatigue life under total strain amplitude controlled deformation. Cyclic stress amplitude controlled high-cycle fatigue characteristics were established at an elevated temperature (150 C). The cyclic stress response, high-cycle fatigue life and fracture characteristics of the alloy are compared with a conventional ingot metallurgy processed counterpart and discussed in light of intrinsic microstructural features, nature and magnitude of stress, and ductility of the material.
