Abstract (Croatian)

Na ispitnom uzorku uslijed vanjskog opterećenja došlo je do pojave loma dijela šasije izrađene od 25CrMo4 čelika. Karakterizacijom materijala i analizom zavara ispitan je utjecaj zavara i ZUT-a na svojstva šasije u području pukotine. Karakterizacija materijala uključuje svjetlosnu i elektronsku mikroskopiju. Analiza zavara uključuje vizualni pregled izgleda zavara, endoskopiju, rendgenska ispitivanja, pronalazak poroziteta i uključina, te mjerenje mikrotvrdoće zavara, ZUT-a i osnovnog materijala.

Abstract

Due to external load, crack has formed on the test sample made of 25CrMo4 steel. Using materials characterization methods and weld analysis to determine the affect of welds and heat affected zone on the chassis properties in the crack area. Material characterization includes optical and electron microscopy. Veld analyzation includes veld visual examination, endoscopy, radiography, finding porosity and incidence, and measuring microhardness of the veld, HAZ, and base material.
