  A bulk metallic glass forming alloy is subjected to shear flow in its
supercooled state by compression of a short rod to produce a flat disc. The
resulting material exhibits enhanced crystallization kinetics during isothermal
annealing as reflected in the decrease of the crystallization time relative to
the non-deformed case. The transition from quiescent to shear-accelerated
crystallization is linked to strain accumulated during shear flow above a
critical shear rate $\dot\gamma_c\approx 0.3$ s$^{-1}$ which corresponds to
P\'{e}clet number, $Pe\sim\mathcal{O}(1)$. The observation of shear accelerated
crystallization in an atomic system at modest shear rates is uncommon. It is
made possible here by the substantial viscosity of the supercooled liquid which
increases strongly with temperature in the approach to the glass transition. We
may therefore anticipate the encounter of non-trivial shear-related effects
during thermoplastic deformation of similar systems.
