20.500.12556/DKUM-26502 Ellipsometric measurements of plastically deformed copper Chemically pure copper (99.99) prepared in the sample of square cross-section (10 x 10 mm2) and length about 50 mm was extremely plastically deformed with the repeated application of equal channel angular pressing. Equal channel angular pressing was applied as an effective technique for producing bulk nanoscaled structures. It is well known that severe plastic deformation of metallic materials often leads to microstructure with ultrafine grains and cross-sections which remain about equal before and after deformation. Optical properties of the sample were studied using spectroscopic ellipsometry in UV-VIS range. The parameters of the sample like copper oxide and surface roughness overlayer were calculated using two-film model together with the Bruggeman effective medium approximation. hydrometallurgical extraction of metals copper true true false Angleški jezik Angleški jezik Neznano 2012-05-31 13:51:24 2012-05-31 13:51:24 2022-04-15 03:41:51 2024-01-03 03:29:57 2009 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669 13589526 0587-4246 URN:SI:UM:DK:VC8OGPLY http://przyrbwn.icm.edu.pl/APP/PDF/116/a116z495.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=35539 Fakulteta za strojništvo 0 0 0
