Merjenje zaostalih napetosti v zvarih na dupleks nerjavnih jeklih : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni program

Muhič, Krystijan

Zaostale napetosti se pojavljajo pri skoraj vseh proizvodnih procesih, kjer v material vnašamo energijo in vplivajo na življenjsko dobo izdelka. Zaključna naloga temelji na teoretičnem pregledu in ... sicer se osredotoča na zaostale napetosti, ki nastanejo v zvarih na dupleks nerjavnih jeklih. Obravnavani bodo varjeni kvadratni in H-profili iz vitkega dupleks nerjavečega jekla. Meritve natezni in tlačnih napetosti so bile opravljene z nedestruktivno metodo nevtronske difrakcije, Izvedena je bila analiza trdote in mikrostrukturna karakterizacija z optično mikroskopijo in difrakcijo s povratnim sipanjem elektronov. S tem je bil ugotovljen volumenski delež posamezne faze in preračunane zaostale napetosti. Največje natezne zaostale napetosti varjenih kvadratnih profilov so bile opažene v bližini zvarov, in sicer za vzorec S-1 in S-2. Pri H-profilu pa so bile največje zaostale napetosti opažene na sredini razpona stranskih plošč in na obeh koncih prirobnice.
