“…In our previous work, 1 at.% addition of rare earth Y was found to improve the GFA of Zr-based BMGs effectively and change the first crystallization phase of Zr 53.8 Cu 29.1 Ni 7.3 Al 9.8 BMG from Cu 10 Zr 7 to CuZr 2 , which is beneficial to controlling the crystallization process and preparing bulk nanocrystalline alloys [ 30 ]. Microalloying of rare earth holmium (Ho) element was investigated to show beneficial effects on the GFA of Fe-based and Zr-based metallic glasses [ 26 , 27 , 28 , 29 , 31 , 32 ]. However, the addition of Ho in the literature is minimal and displayed limited understanding of microalloying effects of Ho [ 26 , 27 , 28 , 29 , 32 ].…”

The effect of holmium (Ho) addition on the glass-forming ability (GFA) and crystallization behaviors of Zr54Cu29Al10Ni7 bulk metallic glass (BMGs) were studied by employing differential scanning calorimetry (DSC), X-ray diffraction (XRD), and transmission electron microscopy (TEM). The characteristic temperatures and activation energies of crystallization were obtained from DSC data. Classical kinetic modes were used to evaluate the crystallization processes of Zr54Cu29Al10Ni7 and Zr48Cu29Ni7Al10Ho6 BMGs. The results showed that Ho addition reduces the activation energy in the original crystallization period of Zr-based BMG and improves the nucleation, which is due to the formation of simpler compounds, such as CuZr2, Cu2Ho, and Al3Zr5.
