Abstract

We found that a Ni-rich alloy with the composition of Ni ₅₀Pd ₃₀P ₂₀ had high glass-forming ability. Bulk glassy alloy rods with diameters up to 7 mm can be easily formed by a water quenching method. Its mechanical properties were measured under compressive load. The bulk glassy alloy exhibits relatively high yield strength of 1780 MPa and good ductility as is evidenced from a large plastic elongation of 7.6% before final fracture. The elastic properties of this bulk glassy alloy were also investigated.
