Abstract:In the present study, amorphous-nanocrystalline phase transformation induced by mechanical milling of full monolithic bulk metallic glasses (based on Zr(65)Al(7.5)Ni(10)Cu(17.5) and Zr(58)Al(16)Ni(11)Cu(15) alloys) has been investigated using X-ray diffraction as well as transmission electron microscopy. Nanocrystals having an FCC structure and a grain size of several 10nm precipitate in the early stages of the milling process and remain stable for long milling duration. The structure changes induced by milling give a new insight on the preparation of amorphous-related alloys when using the method of mechanical milling. (C) 2010 Elsevier B.V. All rights reserved.
