Abstract
Among half-Heusler alloys, MNiSn (M = Ti, Zr, Hf) compounds have been extensively investigated due to their unique crystal structure and promising thermoelectric properties. However, forming the MNiSn half-Heusler single phase directly during the solidification process is challenging, necessitating a prolonged annealing step for homogenization. Rapid Solidification Processing (RSP) was.....

Abstract
The irregular and highly rough surface of AlSi10Mg alloy parts fabricated by metal additive manufacturing technology can result in dimensional instability, poor surface quality and fluid turbulence. Therefore, post-treatments are needed to adjust the surface roughness and irregular surface morphology to satisfy industrial requirements. One of the most promising candidates.....

Abstract
In this study, a high-melting point element, flake type graphite (Gr.), was added to aluminum (Al) to improve the latter’s thermal properties. Al with different particle shapes, spherical, irregular and flake shape, was mixed with graphite. Al–50 vol.% Gr. powders were mixed by a shaking mixer and sintered under the.....

Abstract
This study investigates the application of a unidirectional pulsating traveling magnetic field (UPTMF) for the semi-continuous casting of high-strength aluminum alloy 7075 slabs (350×150 mm). The experimental setup involved a comparative analysis of direct chill (DC) casting and electromagnetic stirring (EMS) with a 5 Hz amplitude modulated U-PTMF and 22.5.....

Abstract
In hydrogen refueling stations, polymer O-rings are used for high-pressure hydrogen containers and transfer pipes to prevent gas leakage. A technology has been developed to measure the hydrogen uptake and diffusivity of the polymer materials used in these O-rings. The process involves charging the polymer material with hydrogen under a.....
