Abstract

Glass-forming ability, thermal behavior and mechanical properties of Ni_80-xPd_xP₂₀ (10at% ≤ x ≤ 35at%) glassy alloys have been investigated. The alloys with Pd contents higher than 25 at% exhibit high glass-forming ability, as is evidenced from the formation of a cylindrical Ni₅₀Pd₃₀P₂₀ glassy rod with a diameter of 21 mm. The Ni-rich bulk metallic glasses show relatively high strength in compression and tension tests. More notably, plastic strains exceeding 2% were obtained for all the metallic glasses at room temperature in compression test.
