Homogeneous deformation of bulk metallic glasses in the super-cooled liquid state

Different Zr–Ti–Al–Ni–Cu bulk metallic glasses have been processed. They have been characterized by neutron and X-ray diffraction in the glassy state and after DSC heating up to crystallization.The homogeneous visco-plasticity of the glasses has been studied in the under-cooled liquid state by compression tests at constant strain-rate and by differential mechanical tests with strain-rate jumps at different temperatures.The flow stress appears …
