The crystallization of Zr65Al7.5Ni10Cu17.5 (Z1) and Zr58Al16Ni11Cu15 (Z2) metallic glasses is investigated. The thermal crystallization end-products of the two alloys are different: tetragonal Zr2Cu and hexagonal Zr6Al2Ni for Z1, while Z2 contained hexagonal Zr2Al, big cubic Zr2Ni and some α-Zr solid solution. Comparatively, their milled-induced crystallization product is identical: a FCC phase for both alloys. Raman spectroscopy suggests that nitrogen has an effect on the formation of this stable final product.
