Ti1−xCrxN thin-film samples were sputter-deposited with lateral composition gradients x = 0.1–0.9 across each sample. In order to determine the effect of Cr content on oxidation, samples were air-oxidized at temperatures ranging from 650 to 950 °C. The extent and type of oxide formed was characterized using X-ray diffraction. Only minor oxidation was observed for the 650–750 °C temperature rang...
The structure, elastic properties and electronic structure of Ti-Al intermetallics including Ti3Al (space group P63/mmc), TiAl I4/mmm) TiAl3 P4/mmm) are systematically studied by first-principles calculations. results show that can exist stably whether Cr replaces Ti or Al. ductility the alloy cannot be improved when is replaced in Cr-doped TiAl3. However, it Al, has better ductility. In Ti3Al,...
Ti-Ni-Si-O nanostructures were successfully prepared on Ti-1Ni-5Si alloy foils via electrochemical anodization in ethylene glycol/glycerol solutions containing a small amount of water. The Ti-Ni-Si-O nanostructures were characterized by field-emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and diffuse reflectance absorption spectra....
پژوهش پیش‌رو ماهیّت عنصری تشکیل‌دهنده ذرات گرد و غبار شامل عناصر اصلی و کمیاب در دو شهر آبادان و ارومیه را در زمان رخداد گرد و غبار و شرایط عادی جوی بررسی نموده است. نتایج حاصله در زمان‌های رخداد گرد و غبار در شهرهای آبادان و ارومیه حاکی از افزایش چشمگیر میزان عناصر اصلی شامل Ca، Al و Mg و عناصر کمیاب P و U نسبت به شرایط عادی جوی می‌باشد. در شرایط عادی جوّی و عاری از گرد و غبار در ایستگاه‌های مذک...

To suppress degradation of the electrical property field-effect transistors, removal C contamination without damaging oxide films is important in semiconductor industry. In addition, to reduce bonding failure, it necessary remove native from metal films. achieve this, atomic hydrogen was generated by decomposition H2 gas on a heated tungsten mesh. This surface treatment referred as annealing (A...
