COMMUNICATION DOI: 10.1002/adem.201000339 Analysis of Ball-Milled ZrAlNiCu Bulk Metallic Glass Powders J. Wu,* S. Margueron, N. Allain-Bonasso, P. Bourson, E. Gaffet, C. Dong, T. Grosdidier* The crystallization of Zr 65 Al 7.5 Ni 10 Cu 17.5 (Z1) and Zr 58 Al 16 Ni 11 Cu 15 (Z2) metallic glasses is investigated. The thermal crystallization end-products of the two alloys are different: tetragonal Zr 2 Cu and hexagonal Zr 6 Al 2 Ni for Z1, while Z2 contained hexagonal Zr 2 Al, big cubic Zr2Ni and some a-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. ADV. ENG. MATER. 2011, 00 ....................................... xx–xx
