摘　　要：Zr-Al-Co-Cu bulk metallic glasses （BMGs） are promising surgical materials. By using the electron concentration criterion for BMG composition design, a series of Zr55.8Al19.a（Co1-xCux）24.8 （x = 0-0.8 at.%） alloys were produced, of which BMG rod samples with different diameters were made by copper mold casting. Among these alloys, the Zr55.8A119.4Co17.36Cu7.44 BMG exhibited a centimeter-scale glass formation size （dmax = 12 mm）, an ultrahigh strength （δy = 2.04 GPa）, a large room-temperature plasticity （εp = 4.0%）, and a fracture toughness （KQ = 120 MPa m^l/2）, as well as good corrosion resistance in phosphate-buffered solution. The attAlnment of the combination of properties as large glass-forming ability with excellent mechanical and corrosion stability would suit the surgical devices applications.Zr-Al-Co-Cu bulk metallic glasses （BMGs） are promising surgical materials.
