The issue, microalloying certain element with positive heat of mixing leading to the enhanced glass forming ability (GFA) in multicomponent alloys, has been investigated by systematic experimental measurements coupled with theoretical calculations. It is found that in the Nb-doped CuZr alloys, strong interaction between Nb and Zr atoms leads to a shortened pair distance. In addition, fraction o...

Possible relationships between measures of glass stability (GS) against devitrification on heating (evaluated by the Hrub€y parameter KH 1⁄4 ðT h c TgÞ=ðTm T h c Þ, and the parameter Kw 1⁄4 ðT h c TgÞ=TmÞ and a criterion of glass-forming ability (GFA) – the critical cooling rate – were investigated by computing non-isothermal crystallization for typical values of the main quantities that contro...

The glass-forming ability (GFA) and the magnetic properties of the [(Fe0.5Co0.5)0.75B0.20Si0.05]96Nb4−xYx bulk metallic glasses (BMGs) have been studied. The partial replacement of Nb by Y improves the thermal stability of the glass against crystallization. The saturation mass magnetization (σs) exhibits a maximum around 2 at. % Y, and the value of σs of the alloy with 2 at. % Y is 6.5% larger ...

By using a combination of state-of-the-art experimental and computational methods, the high glass forming ability GFA of Cu46Zr46Al8 alloy is studied from the view of its atomic packing. Three-dimensional atomic configuration is well established. It is found that Al atoms almost homogeneously distribute around Cu and Zr atoms without segregation, causing the local environment around Cu and Zr a...

The discovery of novel metallic glasses (MGs) with high glass-forming ability (GFA) has been an important area active research for years in materials science and engineering. Unfortunately, the traditional approach based on trial-and-error methods is inefficient, time consuming costly. Therefore, machine learning (ML) recently drawn significant interest as alternative development MGs. In this r...
