中文摘要	Open-cell Zr41.25Ti13.25Cu12.5Ni10Be22.5 bulk metallic glass foams were successfully fabricated by a low-pressure melt infiltration method using crude salts as a space-holder material. Detailed investigations were carried out on the energy absorption property and its underlying mechanism for the present foam. It is found that the foam exhibits high energy absorption capacity and absorbs energy efficiently. Further microscopic observations reveal that the bending of struts, formation and manipulation of multiple shear bands, and microcracking within the material contribute to this foam's energy absorption capability.
