Ni-rich bulk metallic glasses with high glass-forming ability and good metallic properties

Abstract

Glass-forming ability, thermal behavior and mechanical properties of Ni80-xPdxP20 (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. © 2009 The Japan Institute of Metals.
