Abstract

The intrinsic nature of bulk metallic glasses Zr_60+xAl₈Ni_15-xCu₁₇ (x = 0-5 at.%) can be effectively modified by changing the Zr/Ni ratio from 60/15 to 65/10. The crystallization behaviors upon isothermal annealing are also changed from multi-step crystallization to single step crystallization with the variation of the Zr/Ni ratio. Ductility improvement attributed to the retarded crystallization kinetics was proposed based upon the results of indentation experiment and crystallization kinetic analysis.
