Microstructural Parameters and Mechanical Properties of the Thermally Simulated HAZ Samples of T24 Steel

Popis výsledku v původním jazyce

The paper is dealing with microstructural characterization and mechanical properties of thermally simulated parts of the heat affected zone in homogeneous weldments of T24 steel. The study has been targeted on the blunt peripheral weld joints of T24 steel between two tubes, which are an integral part of the production of membrane walls. Investigations on thermally simulated HAZ samples were performed in two states: after simulation (as-welded) and after PWHT 740°C/1h. Thermal cycles for simulation of basic parts of HAZ in homogeneous T24 welds were obtained by real measurements with subsequent corrections based on numerical simulations of welding using Sysweld software. Thermal simulations were carried out on samples of Vallourec &amp; Mannesmann tubes using a TCS 1405 simulator. On the thermally simulated samples the hardness and impact energy were evaluated. Microstructural characterization was carried out using both the light and transmission electron microscopy. Extraction replicas were used for identification of minor phases. Results of thermal simulations were validated on a real weldment. Results on simulated samples reasonably complied with results obtained on the real homogeneous T24 steel weldment.
