Dendritic side branching frequency in materials can be controlled using external periodic forcing like pressure or heating. This study explores how modulation parameters influence this tuning and reveals higher harmonic frequencies in the response.

Area of Science:

  • Materials Science
  • Physics
  • Crystallization Dynamics

Background:

  • Dendritic solidification is a common crystal growth pattern.
  • Controlling side branching is crucial for material properties.
  • External periodic forcing can influence dynamic processes.

Purpose of the Study:

  • To investigate the effect of time-periodic forcing on dendritic solidification.
  • To explore the tunability of dendritic side branching frequency.
  • To analyze the sensitivity to modulation parameters and material properties.

Main Methods:

  • Phase-field calculations in two dimensions (2D).
  • Experimental studies on thin liquid-crystal layers (quasi-2D).
  • Analysis of sensitivity to frequency, amplitude, undercooling, and anisotropies.

Main Results:

  • Dendritic side branching frequency is tunable via oscillatory pressure or heating.
  • Sensitivity analysis reveals key influencing parameters.
  • Observed higher harmonic frequency modes alongside synchronous modes.

Conclusions:

  • External periodic forcing offers a method to control dendritic side branching.
  • Understanding parameter sensitivity is key for precise control.
  • Complex dynamic responses, including higher harmonics, are present in forced solidification.
