The Kirkendall plane, indicating diffusion-controlled interactions, may not be unique and can shift within a reaction couple. This study introduces a new approach to explain the movement of inclusions within the diffusion zone.

Area of Science:

  • Materials Science
  • Physical Chemistry
  • Solid-State Physics

Background:

  • The Kirkendall effect describes the formation of voids or markers shifts due to unequal diffusion rates in alloys.
  • Identifying the precise location of the original interface (Kirkendall plane) is crucial for understanding diffusion mechanisms.
  • Existing models often assume a unique and static Kirkendall plane, which may not hold true in all diffusion-controlled interactions.

Purpose of the Study:

  • To investigate the conditions under which the Kirkendall plane is not unique in diffusion couples.
  • To develop a phenomenological model that explains the migration of macroscopic inclusions within the diffusion zone, mediated by the Kirkendall effect.
  • To provide a more comprehensive understanding of diffusion phenomena in materials.

Main Methods:

  • Utilizing inert marker particles at the initial interface of reaction couples to track marker displacement.
  • Analyzing diffusion profiles and marker positions under various diffusion-controlled interaction conditions.
  • Developing a theoretical framework to phenomenologically describe the Kirkendall-effect-mediated movement of inclusions.

Main Results:

  • Demonstrated that the Kirkendall plane is not necessarily unique in diffusion-controlled interactions.
  • Observed the development of multiple Kirkendall planes or the absence of a distinct plane in certain scenarios.
  • Provided a rationalization for the migration of macroscopic inclusions within the diffusion zone based on the Kirkendall effect.

Conclusions:

  • The concept of a unique Kirkendall plane is an oversimplification for many diffusion-controlled systems.
  • A phenomenological approach is effective in explaining complex Kirkendall-effect phenomena, including inclusion migration.
  • This work advances the understanding of diffusion mechanisms and their impact on material microstructure.
