TL;DR: The development of titanium–copper alloys that have a high constitutional supercooling capacity as a result of partitioning of the alloying element during solidification, which can override the negative effect of a high thermal gradient in the laser-melted region during additive manufacturing.

TL;DR: Grain refinement of cast magnesium alloys, particularly in magnesium-aluminium (Mg-Al) based alloys has been an active research topic in the past two decades, because it has been considered as one of the most effective approaches to simultaneously increase the strength, ductility and formability as discussed by the authors.

TL;DR: The authors combine ultrasound and 3D printing to promote equiaxed and refined microstructures in a titanium alloy and a nickel-based superalloy resulting in improved mechanical properties.

TL;DR: In this paper, an improved method was used to investigate the influence of crystallographic orientation on the corrosion of pure magnesium in 0.1 N HCl, and the corrosion depth and orientation of surface features were mapped against crystalographic orientation for many off-principal magnesium crystals.

TL;DR: In this paper, the poisoning effect of excess Si solute on the grain-refining potency of Al-Ti-B grain refiners in Al-Si casting alloys has been studied in a crystallographic investigation.
