The thermomechanical properties and viscous flow behaviors of the Mg 65Cu25-xAgxGd10(x =0, 3. 10at%, namely, Mg65Cu25Gd10, Mg65Cu 22Ag3Gd10, and Mg65Cu 15Ag10Gd10 bulk metallic glasses in the supercooled viscous region under the loading condition were investigated using the thermomechanical analyzer. In this study, the supercooled viscous temperature windows, the minimum viscosity, the fragility parameter, and the deformability parameter would all be degraded with increasing Ag addition, leading to the negative factors for the micro-forming and nano-imprinting practices. The base Mg65Cu25Gd10) alloy appears to be more promising than the Ag containing alloys when the viscous forming is under consideration.
