Deuterium diffusion and retention in a tungsten-carbon multilayer system
A tungsten-carbon multilayer system deposited by magnetron sputtering was used as a model system to study deuterium diffusion in tungsten, carbon and related carbides. After deposition the as-deposited multilayer films were annealed at different temperatures to achieve different structures. The structural changes due to annealing were investigated by Rutherford backscattering spectrometry and X...
متن کاملImpact of beryllium surface layers on deuterium retention in tungsten
In ITER mixed Be/W layers are likely to form and their retention behavior is unknown. A series of ITER-grade tungsten samples have been exposed in PISCES-B to deuterium plasma at 300oC, with and without beryllium impurity seeding of the plasma. If the beryllium concentration is small, the majority of the incident beryllium is re-eroded from the sample surface and only a few nm thick layer of mi...
متن کاملThe Effect of Different Methods of Heat Treatments on the Retention of Ascorbic Acid in Carrot and Corn
ABSTRACT: The history of food science, technology and nutrition and their expansion in respect of raw material, processing, finished products and nutritional value goes back to many years and is still the interests of many researchers. In this work ascorbic acid has been taken not only as an important and vital vitamin to be investigated during the course of different heat processes but also as...
متن کاملProperties of Boron Steel after Different Heat Treatments
In this article boron steel is analyzed on the example of steel grade B27. In view of the fact that steel is supplied in a state after hot rolling, and the choice of a suitable heat treatment is left to the buyer steel were examined after conventional heat treatments. Steel was studied in state as delivered, after normalization, after quenching and after quenching and tempering at different tem...
