| Abstract: | The glass transition and the crystallization of Zr(65)Al(7.5)Ni(10) Cu(15)Co(2.5) amorphous alloys are studied by Differential Scanning Calirimeter (DSC-7). Through determining the glass transition temperatures and the crystallization temperatures with different heating rates (which has a difference of 2500 times), the continuous heating transition diagram and the critical cooling rate are present. The transition activation energy of glass to undercooled liquid and the glass (undercooled liquid) to crystals are calculated by Kissinger method. |

| Keywords: | glass transition crystallization of undercooled liquid critical cooling rate |
