Abstract
Ovaj završni rad sadrži analizu postupka poboljšanja čelika. Ukratko je opisana toplinska obrada, koja služi kao uvod u poboljšavanje čelika, koja je jedna od njenih najvažnijih vrsta. Teorijski je opisan postupak poboljšavanja čelika, kao i vrste poboljšavanja, klasično i izotermičko poboljšavanje. Opisane su promjene u mikrostrukturi i svojstvima čelika koje nastaju za vrijeme poboljšanja čelika. Opisan je pojam kaljivosti čelika. U eksperimentalnom dijelu ovog rada, proveden je postupak poboljšavanja na komadu od čelika 42CrMo4. Eksperimentalni dio odrađen je u „Laboratoriju za toplinsku obradu i inženjerstvo površina“ Zavoda za materijale na Tehničkom fakultetu u Rijeci. Postupak poboljšavanja proveo se nakon što su odabrani odgovarajući parametri, te se nakon svake faze postupka mjerila tvrdoća obradka. Opisana je oprema koja se koristila za postupak poboljšavanja, te su prikazani i proanalizirani rezultati postupka.
Abstract (english)
This final paper contains analysis of the quenching and tempering steel. Heat treatment is breifly explored, which serves as an intro for quenching and tempering of steel which is one of its most important types. Theoretically are described quenching and tempering and types of it, classic and isotermic quenching and tempering. Changes in microstructure and properities of steel which happen during quenching and tempering are also explained. The term hardenability is described. In experimental part of this paper, quenching and tempering of part made from steel 42CrMo4 has been done. Experimental part was done at „Laboratory for heat treatment and surface engineering“ institute for materials on Tehnical faculty in Rijeka. Process was done after choosing right parameters. After every phase of process, hardness was measured. Equipments for quenching and tempering is described and analysed results of the process are shown.
