Phys. Rev. Lett. 101, 145702 (2008) [4 pages]Stochastic Metallic-Glass Cellular Structures Exhibiting Benchmark StrengthReceived 11 February 2008; revised 17 June 2008; published 3 October 2008 By identifying the key characteristic “structural scales” that dictate the resistance of a porous metallic glass against buckling and fracture, stochastic highly porous metallic-glass structures are designed capable of yielding plastically and inheriting the high plastic yield strength of the amorphous metal. The strengths attainable by the present foams appear to equal or exceed those by highly engineered metal foams such as Ti-6Al-4V or ferrous-metal foams at comparable levels of porosity, placing the present metallic-glass foams among the strongest foams known to date. © 2008 The American Physical Society URL:
