    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.

    摘要： A family of iron-based, phosphor-containing bulk metallic glasses having excellent processability and toughness, methods for forming such alloys, and processes for manufacturing articles therefrom are provided. The inventive iron-based alloy is based on the observation that by very tightly controlling the composition of the metalloid moiety of the Fe-based, P-containing bulk metallic glass alloys it is possible to obtain highly processable alloys with surprisingly low shear modulus and high toughness. Further, by incorporating small fractions of silicon (Si) and cobalt (Co) into the Fe—Ni—Mo—P—C—B system, alloys of 3 and 4 mm have been synthesized with high saturation magnetization and low switching losses.

    摘要： The invention is directed to Pd-based metallic glass alloys useful in biomedical applications having no Ni or Cu. Exemplary metallic glass alloys are represented by AaBb{(Si)100-c(D)c}d, where A may be selected from Pd, and combinations of Pd and Pt, B may be selected from Ag, Au, Co, Fe, and combinations thereof, and D may be selected from P, Ge, B, S. Also, a, b, c and d are atomic percentages, and a ranges from about 60 to about 90, b ranges from about 2 to about 18, d ranges from about 5 to about 25, and c is greater than 0 and less than 100.
