In the present work, the glass formation of Zr59Nb5Cu18Ni8 Al10 alloys of 2 mm
diameter were prepared through casting in water cooled copper mould and in a ribbon
form by the single roller melt spinning method. This study is primarily devoted to
evaluate the results obtained by the two methods. The thermal stability was evaluated
by differential scanning calorimetry (DSC) at a heating rate of 10 °C/mn. The glass
formation, structural properties and morphology of the bulk metallic glass are
presented, including glass transition temperature (Tg) and crystallization temperature
(Tx). The microstructure and phases composition of the alloy have been analyzed using
X-ray diffraction and indicate that the alloy is fully amorphous. The mechanical
properties of bulk Zr59Nb5Cu18Ni8Al10 alloy is obtained by compression tests at room
temperature. The fracture and morphologies after compression test are observed by
Scanning Electron Microscopy (SEM), revealed the fragile plastic of the alloy. The
Energy Dispersive Spectrometer (EDS) micro-analysis is performed by measuring the
energy and intensity distribution of X-ray signals generated by a focused electron beam
on the specimen with a diameter 2 mm.
