TL;DR: In this paper, the nucleation ability of inoculating particles inside the solute diffusion zone around growing grains during alloy solidification is studied using a spherical, equiaxed dendritic grain model coupled with a new modified free growth model to predict the final grain size of cast aluminium alloys with improved accuracy.

TL;DR: In this article, the microstructure and grain refinement of an Al-Ti-B master alloy treated with high-intensity ultrasound in fabrication and remelting process have been investigated.

TL;DR: In this article, the dynamic behavior of ultrasound-induced cavitation bubbles and their effect on the fragmentation of dendritic grains of a solidifying succinonitrile 1 wt pct camphor organic transparent alloy have been studied experimentally using high-speed digital imaging and complementary numerical analysis of sound wave propagation, cavitation dynamics, and the velocity field in the vicinity of an imploding cavitation bubble.

TL;DR: In this paper, the composites of aluminum matrix composites reinforced with graphene nanoplatelets (GNPs) were examined using scanning electron microscopy (SEM), TEM and electron back scattered diffraction (EBSD).

TL;DR: In this paper, an in situ synthesized high volume fraction WC reinforced Ni-based composite coating was fabricated on a mild steel substrate by using a high power diode laser, and three kinds of single-layer coatings of different amounts of W+C powder and Ni60 powder were prepared.
