论文摘要
已经研究了Ti-Ni-ZR散装合金中已知二十面体相的薄膜形式的制备作为底物温度的函数。在室温到350 $^\ Circ $ c的温度下，通过脉冲激光沉积沉积在蓝宝石底物上的膜沉积。形态和结构修饰之后是放牧的发病率，$θ$ -2 $θ$ X射线衍射，传输电子衍射和成像。通过电子探针微分析对化学组成进行了分析。通过次级中性质谱学研究了组成的深入变化。我们表明，脉冲激光沉积在275 $^\ circ $ c中使Ti-Ni-Zr Quasicrystalline纹理的纳米晶体的1 m厚膜形成。
The preparation in thin film form of the known icosahedral phase in Ti-Ni-Zr bulk alloys has been investigated as a function of substrate temperature. Films were deposited by Pulsed Laser Deposition on sapphire substrates at temperatures ranging from room temperature to 350$^\circ$C. Morphological and structural modifications have been followed by grazing incidence and $θ$-2$θ$ X-ray diffraction, transmission electron diffraction and imaging. Chemical composition has been analysed by Electron Probe Micro-Analysis. The in-depth variation of composition has been studied by Secondary Neutral Mass Spectroscopy. We show that Pulsed Laser Deposition at 275$^\circ$C makes the formation of a 1 m thick film of Ti-Ni-Zr quasicrystalline textured nanocrystallites possible.
