Summary: The effect of yttrium (Y) on the glass-forming ability (GFA), mechanical properties and corrosion of (Cu50Z-r43Al7)100-xYx alloys was studied. The addition of Y improved the GFA of Cu50Zr43Al7 alloy, with a GFA of 15 mm obtained for (Cu50Zr43Al7)98Y2. The bulk metallic glasses (BMGs) exhibited limited plastic strain but achieved high compressive fracture strength and Young's modulus. The corrosion resistance of the BMGs was improved by the addition of Y.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.

Summary: In this study, the effect of different yttrium doping levels on the glass-forming ability of copper-zirconium-aluminum-based metallic glasses was investigated from thermodynamic and kinetic perspectives. The amorphous structure of the alloys was confirmed using various techniques, and the correlation between the forming ability and thermodynamics/kinetics factors was established through the analysis of thermal characteristics. The results showed that 2% yttrium doping significantly improved the glass-forming ability of the metallic glasses. Yttrium enhances the forming ability by promoting a more densely packed atomic configuration and scavenging oxygen as an undesirable element.

Summary: In this study, a simple method was used to quantify the castability and glass-forming ability (GFA) of two SIM card slots with different designs, as well as at different casting temperatures. It was found that the Zr55Cu30Ni5Al10 (Zr55) alloy has a wider optimal casting temperature range compared to the Zr52.5Cu25Ni9.5Al7Ti6 (Zr52.5) alloy, indicating better GFA of Zr55. However, within the optimal casting temperature range, the castability of Zr52.5 was significantly better than that of Zr55 due to its lower melting point, poorer wettability to the copper mold, and higher optimal casting temperature. These findings provide guidance for the production of Zr-based bulk metallic glass components.

Summary: In this study, the thermodynamic mechanism and general behavior of spinodal decomposition in high-entropy alloys (HEAs) were investigated. Contrary to the high mixing entropy theory, it was found that increasing the number of elements could increase the possibility of spinodal decomposition. The effects of temperature, entropy, and enthalpy were also clarified, and the high entropy effect on pseudo-binary decomposition was proposed. These findings provide a necessary paradigm for understanding and utilizing spinodal decomposition in HEAs.

Summary: Novel Fe86-xP11C2B1Inx (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) amorphous alloys were developed in this study. After appropriate annealing, Fe85.8P11C2B1In0.2 nanocrystalline alloy with low coercivity (2.9-21.0 A/m) and high saturation magnetization (1.63-1.73 T) was obtained. The nanocrystalline structure was confirmed by XRD and TEM, and In microalloying was found to induce nanocrystallization in FePCB amorphous alloy according to Kissinger's plot. This provides a new approach for developing Fe-based nanocrystalline soft magnetic alloys.

Summary: Microalloying is an effective strategy to enhance the nano-crystallization and improve the soft magnetic properties of Fe-based amorphous alloys. The effect of microalloying of immiscible elements (In and Sn) and miscible elements (Al, Ga, and Ge) in Fe on the crystallization behavior and soft magnetic properties of Fe-P-C-B amorphous alloy was investigated. Microalloying of immiscible elements leads to the formation of fine and uniform alpha-Fe nanograins with low coercivity, while the addition of miscible elements results in the growth of few large alpha-Fe grains and high coercivity. This study suggests a strategy of obtaining amorphous-nanocrystalline alloys with desirable magnetic properties by microalloying of immiscible elements.
