Analiza FSW spoja iz raznorodnih aluminijevih zlitin v vzdolžni smeri varjenja : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programAvbelj, Nejc, strojnikPoleg stalne zahteve zmanjšanja emisij ter prevoznih stroškov na račun teže tovora, so lahki materiali z dobrimi mehanskimi lastnostmi vedno bolj uporabljeni v industriji. Visoko-trdnostne ... aluminijeve zlitine so ene izmed njih, vendar pa jih je s konvencionalnimi talilnimi postopki varjenja nemogoče uspešno spajati, še posebno v primeru spajanja raznorodnih zlitin. Iz tega vidika je postopek varjenja s trenjem in gnetenjem (FSW) izredno perspektiven saj omogoča kakovosten zvarni spoj brez napak tudi v primeru spajanja teh materialov. V zaključnem delu smo iz FSW spoja izdelanega iz raznorodnih aluminijevih zlitin serij 2017A-T451 in 7075-T651 izrezali vzorce ter jih ustrezno pripravili za nadaljnje meritve in analize. Nato smo izvedli podrobne meritve mikrotrdote v vzdolžni smeri zvara v več linijah. Hkrati smo iz vidika preučitve vpliva orodja ter vnosa toplote opravili meritve na različnih globinah pod površjem temena zvarnega spoja. Nato smo vzorce makroskopsko pregledali ter izvedli mikroskopske meritve prehodnih območij zvarnega spoja ter mesta kjer so bili izmerjeni ekstremi mikrotrdot. Profile mikrotrdot smo nato poskušali ustrezno povezati z mikrostrukturnimi značilnostmi FSW spoja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [N.
