Microstructural Effects on the Tensile and Fracture Behavior of Aluminum Casting Alloys A356/357
TL;DR: The tensile properties and fracture behavior of cast aluminum alloys A356 and A357 strongly depend on secondary dendrite arm spacing (SDAS), Mg content, and the size and shape of eutectic silicon particles and Fe-rich intermetallics.
Journal ArticleDOI
Damage by eutectic particle cracking in aluminum casting alloys A356/357
TL;DR: In this article, the strain dependence of particle cracking in aluminum alloys A356/357 in the T6 temper has been studied in a range of microstructures produced by varying solidification rate and Mg content, and by chemical modification of the eutectic silicon.
Journal ArticleDOI
The effect of Mg on the microstructure and mechanical behavior of Al-Si-Mg casting alloys
TL;DR: In this paper, the microstructure and tensile behavior of two Al-7 pct Si-Mg casting alloys, with magnesium contents of 0.4 and 0.7pct, have been studied.
Journal ArticleDOI
Fatigue crack growth and fracture paths in sand cast B319 and A356 aluminum alloys
TL;DR: In this paper, the effect of heat-treatment on the fatigue crack growth and fracture paths in lost foam sand cast B319 and A356 Al has been examined by in situ testing in a scanning electron microscope.

Improved cast aluminum alloy
TL;DR: Aluminum alloys with improved properties are provided in this article, where the alloy comprises about 0 to 2% by weight of at least one rare earth element, about 0.5 to about 14% of silicon, 0.25 to about 2.5% of indium and the remainder of aluminum.
