More Information
Summary:Ni-Fe, Ni-Co, and Ni-Cu-based bulk metallic glass forming alloys are provided. The alloys have critical rod diameters of at least 1 mm and in some instances at least 11 mm. The alloys have composition according to Ni(100-a-b-c-d-e)XaCrbNbcPdBe, wherein X is at least one of Fe, Co, and Cu, the atomic percent X (Fe and/or Co and/or Cu) ranges from 0.5 to 30, the atomic percent of Cr ranges from 2 to 15, the atomic percent of Nb ranges from 1 to 5, the atomic percent of P ranges from 14 to 19, the atomic percent of B ranges from 1 to 5, and the balance is Ni.
