摘要：
Amorphous metal foams and methods of making the same are provided. The amorphous metal foams have properties matching those of natural bone, enabling their use as bone replacement scaffolds. In one embodiment, for example, an amorphous metal foam has a density-dependent stiffness (or Young's modulus, denoted E) ranging from about 640ρ3.75 τo αβouτ 2900ρ0.78, and a density dependent strength (σy) greater than about 8.1ρ2.57, wherein ρ (the density) is less than about 1.7 g/cc.
