Compression tests were conducted on the binary Cu50Zr50 metallic glass in a temperature range below glass transition temperature where deformation mode was inhomogeneous. The yield strength of the glass was found to decrease monotonically with the increase of testing temperature in a non-linear fashion. The strength–temperature relation for the binary glass, as well as several other metallic glass systems, could be well correlated through the concept of stress-induced glass transition. The viscosity in the propagating shear band of the binary glass was also measured and found to be insensitive to the sample size and test temperature.

► We conducted micro-compression tests on a binary CuZr metallic glass at elevated temperatures.
► We established the strength–temperature relation, and uncovered its physical significance to be associated with the stress-induced glass transition.
► We correlated the athermal stress limit of various metallic glasses with the shear resistance of the glass.
