Abstract
The disclosure is directed to Ni—Cr—P eutectic alloys bearing Nb as substitution for Cr that are capable of forming metallic glasses with critical rod diameter of at least 1 mm or more. With further minority addition of Si as replacement for P, such alloys are capable of forming metallic glasses with critical rod diameters as high as 10 mm or more. Specifically, Ni-based compositions with a Cr content of between 5 and 14 atomic percent, Nb content of between 3 and 4 atomic percent, P content of between 17.5 and 19 atomic percent, and Si content of between 1 and 2 atomic percent, were capable of forming bulk metallic glass rods with diameters as large as 6 mm or larger.
