The constraint factor, C, given by the hardness to the yield strength ratio and an indirect measure of the pressure sensitivity of plastic flow in amorphous alloys, of a Zr-based bulk metallic glass was measured as a function of temperature.Results show that, contrary to expectations, C increases linearly from \sim 3.2 to 3.5 within the 300–525 K range. Gradual transition in the shear band dominated deformation mechanism was suggested as a possible reason for the observed increase in C.
