Glass-forming Ni50Zr50 intermetallic compound is containerless undercooled and solidified using electrostatic levitation. Large undercoolings up to ∆T = 300 K are achieved. The dendrite growth velocity of the congruently melting alloy measured as a function undercooling high-speed camera technique. experimental data analysed within sharp interface theory. It found that driving force crystallisation controlling kinetics at < 250 but larger progressively controlled by atomic diffusion. This...
The effective mobility approach is compared with the kinetic energy in terms of sharp interface modeling and phase-field modelling non-equilibrium solute diffusion upon rapid solidification binary alloys. two approaches are equivalent for long range bulk phases, but only can introduce effect to short at a or within diffuse interface. Addition results an unreasonable non-bilinear expression flux thermodynamic driving force free production migration phase field propagation, whereas allows...
In recent years, the non-equilibrium solidification technology is developing very fast while designing of processes still relies on classical theories and empirical relations, which can no longer satisfy increasing need for controlling conditions. The are based several major assumptions, such as linear liquidus/solidus, ideal solution, local equilibrium they usually focus model alloys instead real industrial concentrated multi-component alloys. discrepancies between practical conditions...
