用熔融自旋技术制备了Zr_(1-x)M_x(M=Fe,Co,Ni,Cu和Pd)和Cu_(67.5)Ti_(32.5)合金玻璃体。用变换转鼓切线速度的方法,确定了上述合金形成玻璃态的临界切线速度为31m/s。所有合金玻璃体经X射线衍射分析证明为玻璃态结构。用示差扫描量热器,以不同的升温速率测量了它们的热行为。在Fe_(24)Zr_(76),Ni_(24)Zr_(76)合金玻璃体中呈现出一个放热峰,而Co_(21)Zr_(79),Pd_(24.5)Zr_(75.5),Cu_(45)Zr_(55)和Cu_(67.5)Ti_(32.5)则有两个或三个放热峰。用Kissinger技术确定了各个合金玻璃的结晶激活能。最后讨论了由Miedema模型计算的二元合金的混合热对合金玻璃体形成和稳定性的影响。
Zr_ (1-x) M_x (M = Fe, Co, Ni, Cu and Pd) and Cu 67.5 Ti 32.5 glass were prepared by melt spinning technique. Using the method of changing the tangential velocity of the drum, the critical tangential velocity of the above glass forming glass was determined to be 31 m / s. All the alloyed glass bodies proved to be vitreous by X-ray diffraction analysis. Differential scanning calorimeters were used to measure their thermal behavior at different rates of heating. An exothermic peak appears in the glass of Fe_ (24) Zr_ (76) and Ni_ (24) Zr_ (76) ) Zr_ (55) and Cu_ (67.5) Ti_ (32.5) have two or three exothermic peaks. The Kissinger technique was used to determine the crystal activation energy of each alloyed glass. Finally, the influence of the mixed heat of the binary alloys calculated by the Miedema model on the formation and stability of the alloy glass body is discussed.
