Abstract

Ispitivanje ponašanja niskougljičnih čelika predstavlja veliki interes u znanstvenom svijetu obzirom na njihovo različito ponašanje tijekom procesa deformacije. U ovom završnom radu provedena je termografska analiza niskougljičnih čelika sa i bez dodatka mikrolegirajućeg elementa niobija. Statičko vlačno ispitivanje provedeno je na kidalici uz istovremeno korištenje metode termografije. Ispitivani niskougljični čelici sa 0.035% i bez dodatka elementa niobija pokazali su da mikrolegirajući... More element niobij i brzina razvlačenja imaju utjecaj na raspodjelu naprezanja kod hladne deformacije. Less

Abstract (english)

Testing the behavior of low carbon steels presents a major interest in the scientific world due to their different behavior during the deformation process. In this bachelor thesis a thermographic analysis of low carbon steels was performed with and without the addition of microalloying element niobium. The static tensile test was performed on the testing machine simultaneously using the thermographic method. Examined low carbon steels with 0.035% and low carbon steels without niobium... More showed that microalloying element niobium and stretching speed have an effect on stress distribution in cold deformation. Less
