The effects of temperatures on plastic flow and shear banding of a bulk‐metallic glass in compression were investigated. Temperature significantly affects the plastic‐flow and shear‐banding behaviors. With increasing temperatures from the ambient, the plastic deformation tends to become homogeneous both in time and space; while decreasing temperature from the ambient, it tends to be less inhomogeneous in time, but more inhomogeneous in space. Plastic flow is related to shear banding.
