Thermodynamic evaluation and experimental verification of the glass forming ability of Cu-Zr-based alloys

A liquid to amorphous transition in Cu-Zr diffusion couples at low cooling rate from chemically constrained liquid

“…The formation of up to 20 µm thick amorphous layer from a Cu-20%Zr liquid at low cooling rate was observed. This region of the system is, for liquid to amorphous transition, much less characterised than compositions richer in Zr [17]. Cu-20%Zr quenched from the liquid usually leads to the formation of intermetallic glasses [18].…”

Crystallization kinetics of GdYScAlCo high-entropy bulk metallic glass

“…For more than 60 years of research, several hundred bulk metallic glasses (BMG) were synthesized with dimensions up to tens of centimeters. The majority of the synthesized BMGs are alloys based on one or two basic elements with small additions of elements that increase glass-forming ability and characteristics of materials [2][3][4]. In addition to high glass-forming ability, such materials have a number of unique properties: high thermal stability, high plasticity and soft magnetic properties.…”

Microstructure and Wear Properties of HVAF Sprayed Cu-Zr-Al-Ag-Co Amorphous Coatings at Different Spray Temperatures

“…Therefore, it is necessary to investigate the influences of the spray temperatures, especially near the amorphous alloy's glass transition temperature (T g ), on the microstructure and performance of HVAF sprayed amorphous coatings. Compared with Fe-based and Cu-based amorphous alloys, Cu-Zr-Al-based alloys with the high glass-forming ability (GFA) [32][33][34] have been widely studied, showing great potential to be used in various applications. For example, Cu-Zr-Al-Ag alloy systems that exhibit good antibacterial properties are of great interest in biomedical applications, taking advantage of Cu and Ag elements that are well-known antibacterials [8,12,35].…”
