Diffusion of implanted Mo in the Zr57Nb5Cu15.4Ni12.6Al10 bulk non-crystalline alloy has been researched using secondary ion mass spectroscopy (SIMS). Activation energy Q and pre-exponential factor D0 were obtained to be 1.95 eV and 1.13×10-5m2s-1, respectively. Based on the Stokes-Einstern relation, the viscosity of the Zr57Nb5Cu15.4Ni12.6Al10 bulk non-crystalline alloy was investigated at temperatures below the glass transition, it decreases with the increase of temperature from 1.07×1010 Poise at 593 K to 1.42×108 Poise at 673 K.
