Abstract
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.
