“…Instead, the broad centers of gravity were found to be situated at approxim to 45°, a typical amorphous structure with a steamed broad peak that disapp increase in the angle, which means that it contributed to the excellent glass-f [72,73]. There was no characteristic diffraction peak that appeared with the i coating power; the absence of sharp peaks suggests that there is no long-r ZrCuAlNi films, indicating the glassy state of the ZrCuAlNi films, so it can be d is an amorphous structure, which agrees with the literature [74]. It can be seen composition analysis that the difference in the element ratio of the film was n was not caused by the different element ratios.…”

Zirconium-based metallic glass films are promising materials for nanoelectronic and biomedical applications, but their mechanical behavior under different conditions is not well understood. This study investigates the effects of radio frequency (RF) power and test temperature on the nanostructure, morphology, and creep behavior of Zr55Cu30Al10Ni5 metallic glass films prepared by RF magnetron sputtering. The films were characterized by X-ray diffraction and microscopy, and their mechanical properties were measured by a bulge test system. The results show that the films were amorphous and exhibited a transition from noncolumnar to columnar morphology as the RF power increased from 75 W to 125 W. The columnar morphology reduced the creep resistance, Young’s modulus, residual stress, and hardness of the films. The creep behavior of the films was also influenced by the test temperature, with higher temperature leading to higher creep strain and lower creep stress. The findings of this study provide insights into the optimization of the sputtering parameters and the design of zirconium-based metallic glass films for various applications.

“…Fly ash can be used to stabilize the soil embankment, as an aggregate filler, as an additive for bituminous paving, and as a mineral filler for bituminous concrete for road base construction [45][46][47]. Based on its oxidic composition, containing mainly SiO 2 , Al 2 O 3 , CaO, and Fe 2 O 3 , and its fine powder form, which is able to be directly incorporated into ceramic pastes, fly ash is largely used in the ceramic industry [48][49][50][51][52][53][54][55]. Other fly ash applications include zeolite synthesis [56][57][58] and polymer fillers [59][60][61].…”

This paper presents an alternative way to recycle cathode ray tube glass waste, together with fly ash and kaolin, into new glass ceramic materials. The samples were obtained using three firing temperatures: 700, 800, and 900 °C. The effect of the fly ash/CRT waste ratio upon the materials’ firing shrinkage, apparent density, apparent and total porosity, chemical stability, and compression strength was investigated. The firing shrinkage used as a dimensional stability parameter, a firing shrinkage range between 2.19–8.18%, was positively influenced by the waste mix amount. The apparent density of the obtained materials is positively affected by the heat treatment temperature, rising from 2.09 to 2.93 (g·cm−3), while the apparent porosity decreases with the increase of the firing temperature from 6.08 to 2.24 %. All the studied glass ceramics show very good chemical stability and complete immobilization of the Pb2+ and Ba2+ ions in the glass ceramic matrix. The compression strength of the sintered materials ranges between 1.42–11.83 (N·mm−2), being positively influenced by the kaolin amount and negatively influenced by porosity. The obtained results confirm the viability of the proposed alternative to use CRT waste and fly ash together with kaolin to obtain glass ceramic materials that can be used for outdoor paving applications.
