Directional grain growth from anisotropic kinetic roughening of grain boundaries in sheared colloidal crystals.
The fabrication of functional materials via grain growth engineering implicitly relies on altering the mobilities of grain boundaries (GBs) by applying external fields. Although computer simulations have alluded to kinetic roughening as a potential mechanism for modifying GB mobilities, its implications for grain growth have remained largely unexplored owing to difficulties in bridging the wide...
متن کاملGrain boundary scars on spherical crystals.
We present an experimental system suitable for producing spherical crystals and for observing the distribution of lattice defects (disclinations and dislocations) on a significant fraction (50%) of the sphere. The introduction of fluorescently labeled particles enables us to determine the location and orientation of grain boundary scars. We find that the total number of scars and the number of ...
متن کاملA unified approach to motion of grain boundaries, relative tangential translation along grain boundaries, and grain rotation
We postulate that almost any motion of an interface between two crystals can produce a coupled tangential motion of the two crystals relative to each other which is proportional to the normal motion of the interface. Such translations can produce grain rotations; the special case of the rotations of shrinking included circular cylindrical grains which increase misorientation, as seen in the mol...
متن کاملTexture and Grain Growth in Nanocrystalline Permalloy
The texture evolution accompanied by grain growth was investigated in a nanocrystalline Fe-78wt%Ni alloy, namely permalloy fabricated by using an electrodeposition method. The as-deposited specimen revealed a strong <100>//ND and a weak <111>//ND fibre-type textures. Grain growth took place during annealing beyond 370°C and resulted in the texture change such that the <111>//ND fibre strongly d...
متن کاملBeyond Classical Thermodynamics: Grain Growth
It is my great pleasure to give a talk at the Martin Glicksman Festival. The work which I was going to present here was published recently [1], and I decided to shift the discussion to the motivation of this work, which seems more interesting than the work itself. It is gradually being recognized in various branches of physics that the macroscopic description of solids requires “new thermodynam...
