Abstract

This paper investigates the effects of Ni addition on the glass forming ability (GFA) and mechanical properties in Cu60−xNixZr22Ti18 (x=0∼15) metallic glass alloys. Partial substitution of Cu by Ni in the alloys improved the GFA. By increasing Ni content x from 0 to 6, the supercooled liquid region (ΔTx) and crystallization temperature (Tx) were increased, whereas the liquidus temperature decreased to reach the lowest value at x=6. The lowering of liquidus temperature improved the GFA, and the maximum GFA of 6 mm in diameter was obtained at x=6. The compressive strength and micro hardness of the alloys were raised by increasing Ni content, and the Ni containing alloy showed some macroscopic plasticity after yielding.
