Bulk amorphous Pd41Ni10Cu28P21 alloy has been prepared by water guenching method. The system shows excellent glass forming ability (GFA) with a high value of reduced glass transition temperature Trg, 0.714. Structural analyses indicate that the Pd41Ni10Cu28P21 alloy has a dense packing structure closer to “frozen liquid” than that of amorphous Pd40NyP20, alloy. Experiments on crystalliza-tion reveal that several crystalline phases simultaneously precipitate in the early part of crystallization. Below710 K, a metastable phase forms, and subsequently disappears at elevated temperatures. In addition, the influence of partial substitute of Cu for Nl on GFA has been dlscussed wlth regard to ther-modynamics and kinetics.
