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).Keywords: welding, welded joints, multi-pass weld metal, simulated microstructure, impact toughnessPublished in DKUM: 03.07.2017; Views: 2389; Downloads: 135 Full text (223,13 KB)This document has many files!
