Simulation of structural stability of weld joints of heat-resistant steels.

Original language description

Knowledge of microstructure stabilities is essential for reliable estimations of the lifetime limitations of materials and welded joints at higher temperatures. This information may be deduced from material phase diagrams and from heterogeneous weld joint simulations. The phase diagrams can be calculated using CALPHAD method [1]. This method complemented with appropriate diffusion approach [2], [3] can help us to simulate phase and element profile evolutions inside diffusion-affected zone of weld jointtoo. Thermodynamic database STEEL [4] and kinetic database DIF mentioned in [5] are used. The weld joints are simulated as heterogeneous diffusion couples. The results of the equilibrium calculations are presented as the phase diagram cross-sections of the selected materials: heat resistant steels and weld metals. The same equilibrium calculations offer element activities too. The carbon activity temperature dependences were calculated for individual materials. The observed difference be

Simulace strukturní stability svarových spojů žárovzdorných ocelí.

Czech description

Jsou vypočteny fázové diagramy metodou CALPHAD method za použití vytvořené termodynamické a kinetické databáze. Svarové spoje jsou simulovány jako difúzní páry. Z fázových a chemických simulovaných profilů je usuzováno na mikrostrukturu a mechanickou stabilitu spojení.
