Tensile testing at elevated temperatures

U ovom završnom radu opisane su metode statičkog vlačnog ispitivanja čelika pri sobnoj i povišenim tempraturama definirane normama HRN EN ISO 6892-1:2016 i HRN EN ISO 6892-2:2018. Navedene su izmjene donešene u posljednjem izdanju norme HRN EN ISO 6892-2:2018. Dan je pregled ispitne opreme i aparature te normirani zahtjevi. Eksperimentalni dio rada sastoji se od statičkog vlačnog ispitivanja čelika na sobnoj temperaturi i dvije povišene temperature (200˚C i 400˚C). Dobiveni rezultati su analizirani, utjecajni faktori na rezultate određeni su prema literaturi i donešeni su zaključci.This paper describes tensile testing methods for steel at room and elevated temperatures as defined by HRN EN ISO 6892-1:2016 and HRN EN ISO 6892-2:2018. Changes made in the latest edition of HRN EN ISO 6892-2:2018 are stated. An overview of test equipment and apparatus and standardized requirements are given. The experimental part consists of tensile testing of steel at room temperature and two elevated temperatures (200˚C and 400˚C). Obtained results were analyzed, result influencing factors were determined according to literature and conclusions were reached
