Understanding mechanisms of grain refinement of aluminium alloys by inoculation
TL;DR: For over half a century, grain refinement of aluminium alloys has been achieved by chemical inoculation; current grain refinement practice involves the addition of master alloys before casting, introducing inoculant particles to the melt as mentioned in this paper.

Tensile behavior of dissimilar friction stir welded joints of aluminium alloys
N. Shanmuga Sundaram,N. Murugan +1 more
TL;DR: In this paper, the effects of process parameters and tool pin profile on tensile strength and tensile elongation of dissimilar friction stir welded joints are analyzed in detail, and the results are useful to fabricate the joints with desired tensile properties and to automate the FS welding process.

Comparison of Microstructure and Mechanical Properties of Scalmalloy® Produced by Selective Laser Melting and Laser Metal Deposition.
TL;DR: Investigations show that Scalmalloy® specimens produced by LMD are prone to extensive porosity, contrary to SLM specimens, which is translated to ~30% lower fatigue strength.

Scientific principles of making an alloying addition of scandium to aluminium alloys
TL;DR: In this article, the main regularities characterising the effect of scandium on a structure and properties of aluminium alloys have been found and, based on this, principles of making an alloying addition of Scandium to aluminum alloys and the foundations of a technology for production of wrought semiproducts have been formulated.

The solidification behaviour of dilute aluminium–scandium alloys
TL;DR: In this paper, the authors investigated the solidification behavior of dilute Sc containing Al alloys and found that Sc additions greater than the eutectic composition (0.55 wt%) produced a remarkable refinement in the grain size of aluminium castings, due to the formation of the primary Al3Sc intermetallic phase during solidification.
