In this paper, we investigated the glass-forming ability and mechanical properties of Cu-Hf-Al BMGs. Cu-Hf-Al series glasses were prepared using a quenching method, and their glass-forming ability was studied by X-ray diffraction and differential scanning calorimetry. The elastic, plastic, and fracture properties were studied by compression and shear experiments. The experimental results indicate that Cu-Hf-Al series glasses have excellent glass-forming ability and high hardness, as well as good elastic, plastic, and fracture properties. This study provides a theoretical and experimental basis for further development and application of Cu-Hf-Al series glasses.

Introduction Bulk metallic glasses (BMGs) are aclass of materials that have attracted widespread attention since their discovery in the 1960s. BMGs are amorphous or almost amorphous materials that have high hardness, good wear resistance, and excellent corrosion resistance. In addition, they have excellent mechanical properties, including high strength, high elasticity, and good ductility [1-3]. BMGs have found wide applications in various fields, such as aerospace, electronics, and biomedical
