Abstract
Tema ovog rada je ovisnost tvrdoće o trajanju popuštanja kod poboljšavanja čelika C45 te je objašnjen postupak poboljšavanja sa svim svojim fazama. U nastavku rada objašnjeni su stadiji popuštanja te ponašanje nelegiranih i legiranih čelika pri popuštanju. U eksperimentalnom dijelu rada ispitan je utjecaj trajanja popuštanja na tvrdoću uzorka izrađenog od čelika C45. Opisane su sve faze toplinske obrade, kao i pripreme uzorka za metalografiju i ispitivanje tvrdoće. Dobiveni su rezultati te je zaključeno kako vrijeme popuštanja značajno utječe na tvrdoću.
Abstract (english)
The topic of this thesis is the investigation of the hardness in dependence on the relaxation duration by the improvement process of steel C45 and the whole process is explained through all phases. The remainder of this paper explains the stages of relaxation and behavior of non-alloy and alloy steel for easing. The experimental part investigates the dependence of relaxation duration on hardness of a part made from steel c45. All stages of heating treatment are explained, just like the preparation of the sample (part) for metallography and hardness testing. The results have been obtained and as it follows it is possible to conclude the discharge time significantly affects the hardness.
