Vpliv hladne deformacije na rekristalizacijo in elektromagnetne lastnosti elektropločevineKrižaj, Ažbe, metalurg ...Namen raziskave je bil ugotoviti vpliv skupne hladne deformacije, temperature žarjenja in kritične hladne deformacije na elektromagnetne lastnosti elektro pločevin. Žarjenje, pri različnih ... temperaturah je potekalo v zaščitni atmosferi suhega vodika. Z poizkušanjem smo določili čase potrebne za potek rekristalizacije. Temu je sledilo hladno valjanje za dosego kritične deformacije. Po valjanju smo pločevino žarili po postopku, kot ga zahtevajo mednarodni standardi za izdelavo elektropločevine. Zaradi težav, ki so se pojavile pri hladnem valjanju, nismo mogli izmeriti elektromagnetnih lastnosti po standardnih postopkih. Zato smo se odločili, da le-te določimo napodlagi merjenja orientacij zrn, saj vemo, da želimo imeti čim več zrn s kristalno lego (100). Za te meritve smo uporabljali metodo uklona povratno sipanih elektronov (EBSD). Izbrali smo pločevino, ki je bila žarjena pri 680 [kompozitum]C in tako smo opazovali le vpliv kritične hladne deformacije na število zrn z želeno orientacijo. Ugotovili smo, da se z nižanjem stopnje deformacije veča število zrn z orientacijo (100), kar pomeni, da naj bi pločevina z nižjo stopnjo hladne kritične deformacije imela boljše elektromagnetne lastnosti.Source: Program in knjiga povzetkov = Program and book of abstracts (Str. 47)Type of material - conference contributionPublish date - 2005Language - slovenianCOBISS.SI-ID - 570026
