dc.description.abstractTHE OSCILLATORY GROWTH OF A DILUTE BINARY ALLOY IN RAPID DIRECTIONAL SOLIDIFICATION HAS RECENTLY BEEN DESCRIBED BY A NONLINEAR OSCILLATOR EQUATION, ASSUMING A UNIFORM DIFFUSION CONSTANT OF THE SOLUTE COMPONENT IN BOTH PHASES. IN A MORE REALISTIC MODEL WITH A VANISHING DIFFUSION COEFFICIENT IN THE SOLID PHASE THIS LEADS TO THE FORMATION OF DURABLE LAYERS OF ALTERNATING SOLUTE CONCENTRATIONS. DUE TO THE MULLINS?SEKERKA INSTABILITY, THE HIGH-CONCENTRATION LAYERS COMMONLY FEATURE A DENDRITIC MICROSTRUCTURE. WE CONJECTURE THAT THE MECHANISM BEHIND THIS SO-CALLED BANDED-STRUCTURE EFFECT ALSO APPLIES TO SOME OF THE QUITE INDEPENDENTLY DISCUSSED STRIATION PHENOMENA IN A LARGE NUMBER OF GENERAL CRYSTAL-GROWTH PROCESSES.
