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 …

Grain refinement leads, in general, to a decreased tendency to hot tearing, a more dispersed
and refined porosity distribution, and improved directional feeding characteristics during …

Additive manufacturing, often known as three-dimensional (3D) printing, is a process in
which a part is built layer-by-layer and is a promising approach for creating components …

Abstract Si poisoning on Al-5Ti-B master alloys has been restraining the effectiveness of
grain refinement of hypoeutectic Al-Si casting alloys for over 60 years, and yet the …

Grain refinement not only enhances the mechanical performance of as-cast metallic
materials but also provides an effective mechanism for controlling cast defects, such as …

Poor high/medium-temperature phase stability and/or low room-temperature ductility are
currently bottlenecks of refractory high-entropy alloys (RHEAs) that restrict their high …

The refinement of Al alloys by TiB 2 has been extensively investigated for decades, both in
industry and academia. In order to achieve higher grain refinement potency, it is known that …

The grain refining behaviour of a novel Al-Ti-Nb-B alloy in Al-Si melt with low cooling rate
was in-situ observed by synchrotron radiography. Nucleation and growth of α-Al dendrites in …

To exploit the full potential of the additive layer manufacturing technique it is necessary to
adapt the material to the process via a smart alloy design strategy. To this end, in order to …

A356 alloys are widely used in industries due to their excellent comprehensive performance.
Sr is usually added in A356 alloys to improve their mechanical properties. There have been …
