Using an advancement of a phase field model of multi-grain crystallization developed by Moelans et al., a system of governing equations describing the evolution of multiple crystals in rapidly solidifying samples is formulated. The dynamics of the mo

Four methods for the calculation of interface curvature in cellular automata models for solidification are evaluated. Three of the methods are based on the level-set interpretation of the solid fraction field and calculate the required spatial deriva

Thermodynamic driving forces and growth rates in rapid solidification are analysed. Taking into account the relaxation time of the solute diffusion flux in the model equations, the present theory uses, in a first case, the deviation from local chemic

Resolidification of the mushy zone of multiphase and multicomponent alloys in a temperature gradient is investigated. Experiments of gradient annealing are conducted for a multiphase Cu-40 wt.%Al alloy and an Al-1 wt.%Mg-5 wt.%Si alloy with varying h

The cyclic plasticity of Ni–5at.%W with a strong cube texture was investigated for two different deformation directions and at two different plastic strain amplitudes of 2.5 ⋅ 10−4 and 5 ⋅ 10−4 in a symmetric push–pull-mode. To prevent be

Phase-field analysis for the kinetic transition in an ordered crystal structure growing from an undercooled liquid is carried out. The results are interpreted on the basis of analytical and numerical solutions of equations describing the dynamics of

A method for the investigation of directional solidification in cylindrical metallic samples with diameters of 2 µ m and lengths of 5 cm, embedded in glass capillaries is presented. We estimate the Rayleigh number of the melt inside these samples to

A sharp interface model and a diffuse interface model describing rapid solidification are compared. Both models are based on the assumption of two independent processes at the solid/liquid interface that together consume the available driving force.
