Abstract
U završnom radu ističe se važnost svojstva prokaljivosti čelika prilikom toplinske obrade te utjecaja prokaljivosti na ostala svojstva čelika. Rad je podijeljen u dva dijela. U teoretskom dijelu rada bavi se toplinskom obradom čelika te se stvara podloga znanja potrebnog za izvesti eksperimentalno ispitivanje prokaljivosti na čeliku 30CrNiMo8. U drugom poglavlju objašnjavaju se svojstva vezana za toplinsku obradu, poput tvrdoće i prokaljivosti, nabrojane su metode ispitivanja tvrdoće i prokaljivosti čelika te se objašnjava utjecaj legirajućih elemenata na prokaljivost i općenito toplinsku obradu. U eksperimentalnom dijelu rada navode se karakteristike 30CrNiMo8 čelika, opisuje se korištena oprema i strojevi vezani za Jominyjevu metodu procjene prokaljivosti kojom se ispitivala prokaljivost navedenog čelika, te se opisuje sam postupak Jominy metode, uključujući procese kaljenja, gašenja i mjerenja tvrdoće. Na kraju se određuje prokaljivost strojnog komada MK.17-PJ.86 pomoću dobivene Jominy krivulje, udjela ugljika u čeliku, te poznatog načina i intenziteta gašenja.
Abstract (english)
This bachelor's thesis highlights the importance of hardenability during heat treatment and its effect on other properties of steel. The thesis is split up in two parts. The first part explains the process of heat treatment of steel, which ensures a good background of knowledge needed for the second part, or rather, the practical part in which the hardenability of 30CrNiMo8 steel is tested. In the first part, mechanical properties that are a part of the heat treatment process are explained, such as hardness and hardenability. The effect which steel alloys have on hardenability is also explained. In the second part the manufacturer's characteristics for steel 30CrNiMo8 are introduced, equipment and machines used for the Jominy end quench test for measuring hardenability are described and the process of Jominy's test is explained. Lastly, with data from the Jominy test, known intensity of quenching and known percentage of carbon in the steel, the hardenability of workpiece MK.17-PJ.86 is quantified.
