Relation between self diffusion and interdiffusion in Al-Cu melts
We compare the experimental interdiffusion constants DAlCu in liquid Al81.3Cu18.7 at% to the experimental Cu self diffusion constants DCu in a similar Al80Cu20 at% melt. DAlCu are measured by an X-ray radiography technique and DCu are measured by the quasielastic neutron scattering method. It was found that DAlCu is enhanced by a factor of 3 with respect to DCu. The relation between DAlCu and D...
متن کاملSelf diffusion coefficients of TBBA
2014 The diffusion coefficients D~ and D~ have been measured by a two pulse NMR spin echo with rotatable pulsed field gradient in the nematic regime of TBBA. In this range we find D~ /D~ ~ 3. The diffusion process in both the nematic and the smectic A phases is discussed briefly. LE JOURNAL DE PHYSIQUE TOME 38, MARS 1977,
متن کاملFirst principles calculation of the interdiffusion coefficient in binary alloys.
The atomic mechanisms of diffusion in alloys are complex due to the variations of migration energies with environment and the correlations induced by short-range order between the different components. We present a first-principles approach for calculating vacancy-mediated diffusion coefficients in crystalline binary alloys and apply it to obtain the interdiffusion coefficient of Al(1-x)Lix. Th...
متن کاملThe interdiffusion coefficient in two-component polymeric mixtures
2014 Starting from the Liouville equation we derive equations for density and concentration fluctuations in two-component polymeric liquids. An exact expression for the interdiffusion coefficient is obtained. As examples we consider mixtures of labelled molecules and the case of polymers solved in a low molecular weight liquid. The relation of the general formula to two widely used approximate ...

اهمیت این پژوهش در آن بود که به گفت? بسیاری از پژوهشگرانِ حوز? بازبینی ترجمه، ادبیات موجود در این زمینه به لحاظ نظری و عملی چندان قوی نیست و بخش های موجود نیز برداشت مناسبی از این مرحل? فرایند ترجمه ندارند، اگرچه اخیراً توجه به آن به صورت نظام مند افزایش یافته است. در عین حال، پژوهش های موجود از یک سو بر دگربازبینی بیشتر از خودبازبینی تأکید دارند و از دیگر سو تنها به لحاظ نظری به این موضوع می پرد...
