Abstract
U ovom radu je pisano općenito o toplinskoj obradbi kaljenja i toplinskoj obradbi popuštanja čelika. Ova dva postupka toplinske obrade su jako bita jer se odvijaju uvijek u paru. Prvim dijelom ovog rada predstavljen je Uptonovim dijagramom koji daje podatke o potrebnim iznosima pothlađivanja austenita, a u drugom dijelu predstavljen je TTT dijagramom koji prikazuje strukturne promjene pri različitim režimima gašenja austenitiziranog čelika. U drugom dijelu rada govori se o kaljivosti čelika, odnosno o važnosti stupnja zakaljenosti i prokaljenosti čelika. Vezano za svojstvo prokaljivosti razmotreni su postupci ispitivanja prokaljivosti. Opisan je utjecaj legiranja na toplinsku obradbu i na TTT dijagram. U trećem dijelu rada opisani su postupci kaljenja čelika. Opisan je klasični postupak kaljenja, kaljenje postupkom slomljenog gašenja te kaljenje u toploj kupki. Četvrtim dijelom opisuje se popuštanje čelika. Niskotemperaturno, srednjetemperaturno i visokotemperaturno popuštanje s danim temperaturama pojedinog postupka te primjenom svakoga. U petom dijelu rada opisani su postupci i svrha poboljšavanja, odnosno kakav utjecaj ima samo poboljšavanje na mehanička i tehnološka svojstva čelika.
Abstract (english)
This work is generally about heat treatment quenching and heat treatment tempering of steel. These two methods of heat treatment are very important to achieve the required properties of some engineering construction. The first part of this paper was presented with Uptons diagram that gives us a perception of the required amounts of cooling for austenite, and the second part presents the TTT diagram showing the structural changes in different modes of cooling autenite. The second part deals with the germination of steel, and the importance degree of quench hardening and quench hardening steel. With regard to property hardenability reviewed the testing procedures hardenability. The influence of alloying on the heat treatment and the TTT diagram. In the third section describes the procedures hardening steel. Described is a classic process hardening, tempering process broken quenching and tempering in a warm bath. The fourth section describes Tempering of Steel. Low temperature, medium temperature and heat temperature with each temperature process and application of each process. In the fifth part of the paper describes the procedures of Improvement of Steel, and what kind of impact has only improve the mechanical and technological properties of steel.
