Abstract In order to approximate Gibbs energy functions, a semi-automated framework is introduced for binary and ternary material systems, using Calphad databases. To generate formulations by means of second-order polynomials, the includes precise approach. Furthermore, an optional extensional step enables modeling systems in which direct generation leads unsatisfactory results representation thermodynamics. results, when representing Within this extension, commonly generated functions are...
For the first time, experimental processing condition of a rotating directional solidification is simulated in this work, by means grand-potential-based phase-field model. To simulate solidification, new simulation setup with temperature field introduced. The newly developed configuration can be beneficent for more precise study ongoing adjustment mechanisms during gradient controlled processes. Ad hoc, ternary eutectic system Bi-In-Sn three distinct solid phases α,β,δ studied paper. system,...
The self-propagating reaction in binary Al/Ru multilayers with two different bilayer thicknesses (89 and 178 nm, respectively) forming single-phase AlRu intermetallic compound is investigated experimentally by means of phase-field simulations. Experimentally, the time-temperature evolution free-standing films was recorded a high-speed pyrometer, resulting microstructure determined from electron backscatter diffraction measurements. model constructed based on minimization grand potentials for...
