The metallic glasses AgxCu50-xZr50 are prepared by an induction furnace followed by melt spinning in vacuum. It is found that amorphous alloys can be obtained in the range xc of the metallic glasses AgxCu50-xZr50 with x = 2, 4, 6 and 10 are obtained. The activation energys En of crystallization are determined by the Kissinger method. It is shown that the bigger is the x in metallic glasses AgxCu50-xZr50, the less stable is the glasses. A comparison of the study on the crystallization of the glasses in argon with that in the air suggests that the second exothermal peaks are oxidation peaks.
