Hydrogenation of Zr-based metallic glasses and quasicrystals
Zr-based metallic glasses and quasicrystals were electrochemically charged with hydrogen. Hydrogen absorption/ desorption as well as the in ̄uence of hydrogen on the formation and stability of quasicrystals were studied by means of X-ray diraction, electron microscopy, dierential scanning calorimetry (DSC) and thermal desorption analysis (TDA). In Zr69:5Cu12Ni11Al7:5 absorption kinetics and st...
متن کاملCombined EXAFS and X-Ray Scattering Investigation of Amorphous Zr-Based Alloys
EXAFS spectra for all K absorption edges and X-ray scattering data have been obtained on an amorphous Fe-Zr sample prepared by mechanical alloying and a rapidly quenched Co-Zr one. Partial pair distribution fnnctions have been determined as a solution of an inverse ill-posed problem for the system of integral equations describing combined experimental data. For Fe-Zr and Ca-Zr amorphous alloys ...
متن کاملOverview of the standard EXAFS data analysis procedure Introduction Interpretation of EXAFS data is normally based on the EXAFS equation
with appropriate accomodation for forward scattering (\focussing e ect") for higher shells, and inclusion of higher cumulants as necessary. The aim of data analysis is to determine the distances, coordination numbers, disorder parameters and types of atoms in the various coordination shells for the \unknown" sample. The extent to which this is possible depends on the nature of the system, the q...

تعارفات کنش های گفتاری هستند که افراد در زندگی روزمر? خود به منظور برقراری دوستی یا تداوم روابط مسالمت آمیز به کار می برند. ساز و کار تعارف مختص زبان انگلیسی یا هر زبان دیگری نیست و پدیده ای است جهانی و در همه زبانها حضور دارد. تفاوتی که از این نظر در زبانها و فرهنگ ها وجود دارد مربوط به پاسخ به این کنش گفتاری در گفتمان است. این مطالعه به بررسی تنوع پاسخ های انگلیسی و عربی به کنش گفتاری تعارف د...
