| 摘 要： | 采用铜模铸造法制备了Cu60Zr29Ti11大块非晶合金,用X射线衍射仪、三点压弯式黏度仪对该非晶合金的动力学性质进行了研究.测定了大块非晶合金Cu60Zr29Ti11在过冷液相区的黏度,得到了它的动力学脆性系数m=31,以及流变激活能E=63.4kJ/mol.表明大块非晶合金Cu60Zr29Ti11是一种强液体,有较强的非晶形成能力,形成非晶比较稳定.分析了合金在过冷态的流变激活能变化规律,发现流变激活能的变化并不符合Kivelson的Super-Arrhenius公式.

| Abstract: | Cu60Zr29Ti11 bulk metallic glass rod was casted by copper mold casting method.The dynamic viscosity near the glass transition region for Cu60Zr29Ti11 was measured using three-point beam bending methods.The fragility parameter m and active energy for viscous flow were calculated to be fragility parameter m=31 and activation energy for viscous flow E=63.4 kJ/mol respectively.It is shown that the supercooled liquid of Cu60Zr29Ti11 alloy is strong liquid.It was found that Kivelson's super-Arrhenius equation is ... |
