Metallic Glasses and Amorphous Alloys

ABSTRACT Motivated by growing demand in electronics, automotive, photovoltaic, and architectural applications, thin‐glass products offer substantial potential for material savings and reduced environmental impact, yet their widespread adoption is limited by mechanical instability and reliance on non‐float manufacturin…

Abstract This study investigates the influence of heat treatment and cooling rate on the phase transformation behavior of a commercially obtained Ti–rich NiTi shape memory alloy (nominal composition Ni–47 at% and Ti–53 at%). The microstructural evolution, phase constitution, and transformation characteristics were sys…

Invar 36 combines an exceptionally low coefficient of thermal expansion (CTE) with limited hardness, which restricts its use in mechanically demanding precision applications. Here, planar‐flow melt spinning was used to refine the microstructure without changing the nominal alloy composition. Four combinations of wheel…

Abstract In this study, the effects of different heat treatment temperatures (650 °C, 750 °C, and 850 °C) on the phase transformation behavior, microstructure, thermodynamic parameters, and microhardness of the NiTiCuW alloy, produced by adding tungsten (W) to the NiTiCu shape memory alloy, were investigated. The crys…

At particle-level engineering, this study mainly focused on the issues of microstructural heterogeneity and the high oxidation susceptibility of Cu-Al-Ni shape memory alloys (SMAs) suitable for high-temperature actuation. Initial powders of Cu (82–83 wt.%) and Al (14–15 wt.%) were first milled mechanically and the Cu-…

Abstract Additive manufacturing offers efficient material usage and enables customized shape designs that are difficult to achieve with conventional methods. This study investigates the binder jetting of Fe-50Ni soft magnetic alloys, which are widely used in transformers, inductors, and motors due to their high flux s…

In this study, Nd-Fe-B nanoparticles with permanent magnet properties were synthesized from elemental raw materials using the mechanical alloying (MA) method and subsequently encapsulated with graphitic carbon shell to enhance their thermal and chemical stability for potential electronic applications. Alloy compositio…

This study investigates the effect of 1 at.% rare-earth (RE =Sm, Gd, Dy) addition on the structural, mechanical, magnetic, and radiation shielding properties of CoFeNiMnTi high-entropy alloys produced by arc melting. X-ray diffraction results reveal an FCC-dominant structure accompanied by secondary Laves-type phases,…

Abstract The objective of this study was to evaluate the photocatalytic degradation of a methylene blue dye solution by Fe–Co based amorphous ribbons with different compositions. In order to assess the photocatalytic activity of the amorphous ribbons, analysis was conducted under UVC, UVA and visible irradiation. The…
