| 摘 要： | 利用实时小角中子散射实验研究了非晶态Cu12.5Ni10Zr41Ti14Be22.5合金相分离的动力学标度性质．通过对相分离过程中实时小角中子散射谱进行详细的标度分析，揭示出散射函数S（q，t）（q为散射波矢，t为时间）在相分离的早期即达到动力学标度态，从而证明动力学标度假设也适用于描述深过冷液态的相分离过程

| Abstract: | The dynamic scaling of phase separation in amorphous Cu12.5Ni10Zr41Ti14Be22.5 alloy has been investigated by means of smallangle neutron scattering. A detailed scaling analysis of the scattering function indicates that the dynamic scaling state of the scattering is reached in the early stage of the phase separation. We demonstrate that the dynamic scaling hypothesis can be applied to the phase separation sequence in deeply supercooled liquid. |
