Weld Joints Simulations 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. The heat-resistant steels (alloying base: Cr, Ni, Mo, V, C, N) and their weld joints are objects of our study. Thermodynamic database STEEL [4] and kinetic database DIF mentioned in [5] are used. The particullar results of the equilibrium calculations are presented as the phase diagram cross-sections of the selected heat-resistance steels. The same equilibrium calculations offer element activities too. The carbon activity temperature dependences were calculated for individual steels

Simulace svarových spojů žáropevných ocelí
Czech description
Pro oceli na bázi Cr, Ni, Mo, V, C, V jsou predikovány fázové diagramy metodou CALPHAD. Pro sledované oceli jsou vypočteny aktivitní teplotní závislosti uhlíku. Je sledován i případ difúze proti koncentračnímu spádu. Součástí práce je simulace difúzníchprofilů sledovaných kombinací svarových spojů.
