In contrast to previous observations of a slight increase in glass transition temperature (Tg) under hydrostatic pressure, we report, for the first time, a drastic reduction of Tg(40K/500MPa) induced by shear stress in a Zr46.75Ti8.25Cu7.5Ni10.0Be27.5bulk metallic glass, which gives rise to the experimental observation of the drastic decrease in flow temperature while a compressive stress was applied. The significant Tgreduction is attributed to a large activation volume of relaxation ΔVτunder shear stress (126Å3), and can be quantitatively interpreted in terms of the free volume model.
