Abstract
Glavna tema ovog završnog rada je procjena dubine prokaljivanja strojnog dijela MJ.20- PP.43. U teorijskom dijelu rada opisana je toplinska obrada materijala pomoću dijagrama postupaka toplinske obrade i Fe-Fe3C dijagrama. Također navedene su i objašnjene fazne pretvorbe čelika. Pojašnjeni su pojmovi poput kaljenja i prokaljivosti. Navedene su i metode prokaljivosti kao što su totalna (teorijska) prokaljivost, Justova metoda utvrđivanja stupnja zakaljenosti, Grossmanov postupak kvantifikacije, Grossmanov proračun idealnoga kritičnog promjera i Jominijeva metoda kvantifikacije prokaljivosti. U drugom dijelu ovog završnog rada opisan je praktični dio, odnosno utvrđivanje prokaljivosti strojnog dijela MJ.20-PP.43. Zaključeno je da strojni dio MJ.20-PP.43. ne ostvaruje zahtjeve prokaljivanja.
Abstract (english)
The main topic of this final paper is the depth assessment of hardening of the machine part MJ.20-PP.43. The heat treatment of the materials is described in the theoretical part of the paper, using heat treatment process diagram and Fe-Fe3C diagram. Phase transformations of steel are also listed and explained. Terms like tempering and hardenability are described.The hardenability methods, like total hardenability method, Just's method of determining the degree of hardening, Grossmann's quantification procedure, Grosmann's calculation of an ideal critical diameter and Jominy methods of quantification of hardenability are listed. The second part of this paper describes the practical part, that is, determination of hardenability of the machine part MJ.20- PP.43. It is concluded that machine part MJ.20-PP.43. does not meet the hardening requirements.
