MECHANICAL-PROPERTIES OF AL-Y-NI AMORPHOUS RIBBONS

Mechanical properties for two series of amorphous AI-Y-Ni ternary allo ys were measured. Both series of alloys can be divided into two distin ct groups. Those whose primary crystallization proceeds by growth of q uenched-in Al nuclei and those which show a clear glass transition and their crystallization product is more complex. The Young's modulus, r anging from 82.3 to 45.5 GPa in these series of alloys, is found to be correlated to the crystallization temperature and thermal behavior as well as the crystallization product implying that the mechanical prop erties depend on the short-range order in the glass.
