An efficient alloy design for bulk metallic glasses (BMGs) assisted by a composition-configurational entropy (C-CE) diagram has been proposed by introducing a feature of high-entropy (HE) alloys that are defined by an equi-atomic alloy with five or more elements. The proposed alloy design compensated for a shortcoming in determining the compositions of BMGs and led to success in forming a Pd20Pt20Cu20Ni 20P20 HE-BMG with a maximum diameter of 10 mm. The C-CE diagram demonstrates the equi-atomicity of alloys, providing candidates for HE-BMGs. The alloy design for HE-BMG will promise opening up the new cutting-edge in both HE alloys and BMGs.
