Summary: Experimental viscosity data for (GeSe2)x(Sb2Se3)100-x melts obtained by PAMFT were fitted using the MYEGA equation over a broad temperature range. The study analyzed fragility concepts for the studied glass-forming system and developed a simple procedure for viscosity data extrapolation, discussing its validity.

Summary: This study investigates the thermodynamics and kinetics of a non-equiatomic high entropy metallic glass (HEMG) with a critical size for glass formation over 50 mm. The research finds that the HEMG has the lowest thermodynamic driving force against crystalline phase formation and exhibits ultrastrong behavior near the glass transition. The alloy also has a higher fragility index compared to typical metallic glass formers reported so far.

Summary: In this paper, a convolutional neural network (CNN) model was used to investigate the glass forming ability (GFA) of bulk metallic glasses (BMGs). By training and testing with a large number of alloy compositions, the study shows that machine learning methods have great potential in guiding the design of new BMG materials.

Summary: This study proposes a random forest regression model based on the metal alloy composition dataset to predict the glass forming ability of bulk metallic glasses. By screening feature parameters and optimizing hyperparameters, the accuracy of the model has been improved, revealing the importance of characteristic temperatures and topological structure parameters in describing the formation of alloy glasses.

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: 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: Magnetic cooling is a promising eco-friendly technology that requires the search for novel functional materials. Gd-based metallic glasses show potential as solid-state refrigerants, but their magnetic properties can be improved. Through element substitution in the alloy components, it is possible to enhance glass-forming ability and overall performance of the materials.

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: This study proposes an improved deep neural network (IDNN) model based on the DenseLoss function to predict the glass-forming ability of bulk metallic glasses (BMGs). The IDNN model has better generalization capability and achieves the highest R2 score of 0.841 in the test set. This research highlights the importance of addressing the Dmax imbalance problem for improving the accuracy of ML models in predicting Dmax and has significant impact on the discovery of novel BMGs.
