We report a scaling collapse of the temperature dependence of structural relaxation in 12 model metallic glass-forming liquids by introducing a characteristic temperature and characteristic time scale under constant dynamic heterogeneity condition. Moreover, we find the onset temperature of cooperative motions,TA, separating Arrhenius and non-Arrhenius behaviors of the relaxation time turns out to be one of the characteristic temperatures, which is evidenced by the constant dynamic heterogeneity atTAfor all systems investigated. Our findings reveal a new dynamic signature hidden inTAand offer a new perspective, i.e., constant dynamic heterogeneity condition, to study metallic glass-forming liquids.
