TL;DR: In this article, a nano-scale scandium rich phase, identified as AlSi 2 Sc 2 (V-phase) uniformly distributed in the alloy, was found to have high matrix hardness (1.34 GPa) in contrast to 1.04 GPa observed in the case of binary Al-Si alloys by nanoindentation.

TL;DR: In this article, the influence of spray deposition process on the refinement of silicon phase and the tribological performance of hyper-eutectic Al-Si alloys is reported.

TL;DR: In this paper, the authors used spark plasma sintered from corresponding gas-atomized powders and showed significant ductility of as high as 85% compressive strain without failure even with the presence of relatively higher weight fraction of the brittle silicon phase.

TL;DR: In this paper, the effect of Si morphology on the microstructural stress distribution of the as-cast and as-sprayed alloys was estimated by simulating uni-axial tensile loads on microstructures using Object Oriented Finite Element code (OOF2).

TL;DR: In situ age hardening phenomenon observed in as-sprayed Al-Sc binary alloys is reported in this article, along with substantial grain refinement in the as-Sprayed alloys exhibited hardness in the range of 605 MPa (Al-0.3 ) to 923 MPa(Al- 0.8 ) that are comparable to the optimum hardness values typically obtained by age hardness in similar as-cast alloys.
