Seaweed growth in alloys exhibits tip splitting dynamics, with frequency related to velocity by a power law (f~V1.5). This behavior aligns with theoretical models and is influenced by material anisotropies.

Area of Science:

  • Materials Science
  • Physics of Materials
  • Solidification Science

Background:

  • Directional solidification is crucial for controlling material microstructure.
  • Understanding crystal growth morphology, like seaweed patterns, is key to predicting material properties.
  • Tip splitting is a complex phenomenon observed in various growth processes.

Purpose of the Study:

  • To experimentally investigate the tip splitting dynamics during seaweed growth.
  • To establish a quantitative relationship between tip splitting frequency and growth velocity.
  • To compare experimental findings with theoretical predictions of a tip splitting model.

Main Methods:

  • Utilized directional solidification of succinonitrile alloys.
  • Observed and analyzed the tip splitting morphology during crystal growth.

Related Experiment Videos

  • Measured tip splitting frequency (f) and growth velocity (V).
  • Developed and presented a theoretical tip splitting model.

    • Main Results:

    • Observed alternating left and right tip splitting in seaweed morphology.
    • Determined a power law relationship: tip splitting frequency f is proportional to growth velocity V to the power of 1.5 (f~V1.5).
    • Demonstrated that small anisotropies lead to varied seaweed morphologies.

    Conclusions:

    • The experimental results confirm the predictions of the presented tip splitting model.
    • The power law relationship provides a quantitative understanding of tip splitting dynamics.
    • Anisotropy plays a significant role in determining the specific seaweed morphology observed.
