Interface kinetics and solidification of alloys: A discussion of some phenomenological models

摘要: Abstract We discuss various phenomenological descriptions of uniform interface kinetics in binary mixtures. show that the linearized description provided by out-of-equilibrium thermodynamics is unambiguous and internally coherent. how simple microscopic pictures atomic attachment are reflected values corresponding Onsager coefficients. far-from-equilibrium models Aziz Jackson-Gilmer-Leamy relationship between solute trapping interspecies drag. propose another type model which interaction two species catalytic type. such an may give rise to oscillatory modes growth, i.e. kinetically-induced striations solid alloy.
