采用x射线衍射、扫描电镜和跃迁电镜以及差示扫描量热法(DSC)研究了电化学沉积制备的Ni纳米晶纳米线(NNW)模型体系的生长动力学和热稳定性。结果表明,在400 ~ 600℃范围内,Ni-NNW的热稳定性主要受微观组织运动和晶界旋转机制的影响。Ni-NNW在接近熔点时经历瑞利不稳定性。在瑞利相变中观察到的碎片分离比理论预期的要大得多。
The growth dynamics and the thermal stability of a Ni nanocrystalline nanowire (NNW) model system fabricated using electrochemical deposition has been investigated using X-ray diffraction, scanning and transition electron microcopy, and differential scanning calorimetry (DSC). It has been found that the thermal stability of the Ni-NNW is dominated by the microstructure movement and the grain boundary rotation mechanism at temperature ranging from 400 to 600°C. The Ni-NNW experiences the Rayleigh instability at temperature approaching the melting point. The observed fragment separation in the Rayleigh phase-transition is much greater than that expected theoretically.
