20.500.12556/RUL-96354 Mikrostrukturne in mehanske lastnosti Al-Cu zvarnih spojev Microstructural and mechanical properties of Cu-Al welded joints Cilj diplomske naloge je bil doseči zvarni spoj med aluminijem in bakrom z difuzijo. Vzorci cilindrične oblike so se spajali pri različnih temperaturah in časih. Spojeni vzorci so se analizirali s svetlobno in elektronsko vrstično mikroskopijo. Na zvarnem spoju se je izvajala EDS analiza kemijske sestave. Merila se je velikost spoja in velikost prisotnih plasti intermetalnih plasti (CuAl2, CuAl, Cu12Al9 in Cu9Al4). Pri vseh spojih so bile prisotne razpoke, ki so potekale skozi evtektik, razen v nekaterih primerih, kjer so bili prisotni lokalni spoji. Ugotavljal se je vpliv temperature in časa na velikost spoja in velikost intermetalnih plasteh. In this thesis the aim was to create a bond between an aluminum and copper specimen through diffusion bonding. The cylindrical shaped specimens were bonded at various temperatures and times. The interface of the joined couple was analysed by optical microscopy and field emisson scanning electron microscopy. An EDS analyse of the chemical composition was made on the couples interface. The size of the joint and the the present intermetalic layers size were messured (CuAl2, CuAl, Cu12Al9 in Cu9Al4). All the joined samples were cracked through the eutectic layer, except in some cases there were present local joints. The influence of tempreture and time on the size of the joint and the size of the present intermetalic layers were examinate. difuzija difuzijsko spajanje baker aluminij intermetalne spojine diffusion diffusion bonding copper aluminum intermetalic compounds true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-29 07:15:36 2017-09-29 07:15:37 2022-08-12 11:16:43 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 58287 535.pdf 535.pdf 1 DA8CA9E5D3EC8E59C9147AA618C68266 05f08419dceca2488ca655a825a8fcb90bd60f2ac627f5656a4c1a9ee492c2d7 e44f31b2-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/7a4cd544-afeb-4d66-be71-bc1884b731dd https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=105014 Naravoslovnotehniška fakulteta 0 0 0
