Abstract

The influence of weld thermal cycle on the micrstructural changes in weld metal by use of the simulated microstructures. We examined the kinetics of the formation of austenite from the starting microstructure. The simulated microstructures were prepared by the application of simulated thermal cycles with different peak temperatures on a sample of real single-pass weld metal. The reproduction of thermal cycles were carried out by the SMITWELD simulator. Special attention was dedicated to the influence of thermal cycle on the formation of microstructures, which can be potential triggers of brittle fracture (local brittle zones).

Secondary title: Utjecaj simuliranog termičkog ciklusa na stvaranje mikrostruktura višeprolaznog zavara
Secondary abstract: U ovom radu je eksperimentalno analiziran utjecaj termičkog ciklusa kod zavarivanja na mikrostrukturne promjene u zavaru. Simulirane mikrostrukture bile su pripremljene pri termičkim ciklusima različitih maksimalnih temperatura na uzorcima realnog jedno prolaznog zavara. Simulirani termički ciklusi bili su izvedeni na SMITWELD simulatoru termičkog ciklusa. Posebna pažnja bila je usmjerena utjecaju termičkog ciklusa na stvaranje mikrostruktura, koje bi mogle biti potencijalna mjesta za krti lom (lokalno krte zone).
