Crystallographic orientation

  • 31.2: The Orientation of a Lattice Plane is Described by its Miller Indices.
    The orientation of a surface or a crystal plane may be defined by considering how the plane (or indeed any parallel plane) intersects the main crystallographic axes of the solid.

  • What are crystallographic orientations?

    "Crystal orientation" is defined by the plane (Miller) indices of the lattice plane of a crystal.
    In observation of an electron microscope image using a TEM, the particular crystal orientation (usually, orientation expressed by the low-order indices) is aligned to the direction of the incident electron beam..

  • What is crystallographic preferred orientation?

    Crystallographic preferred orientations (CPOs) in deformed rocks are commonly interpreted as resulting from crystal plastic deformation mechanisms, where deformation is achieved by the movement of dislocations..

  • What is orientation relationship in crystallography?

    Orientation Relationship (OR): Relation between specific planes and directions of two crystals on either side of boundary. • During most phase transformations, some favored orientation relationship exists between the parent and the product phases which allows the best fit at the interface between the two crystals. •.

  • What is the meaning of orientation of a crystal?

    Crystal orientation is defined by a standard consumable seed, which can be precut to a variety of different orientations using the same puller interface, such as \x26lt;100\x26gt;, \x26lt;111\x26gt;, \x26lt;110\x26gt;, \x26lt;211\x26gt;, and others.

In order to describe a crystallographic orientation, two coordinate systems must be defined: one for the sample, referred to as XS and one for the crystallite, XC (Figure 3). The choice of sample axes is somewhat arbitrary; however, the choice usually follows the sample shape or processing used to form the sample.

Does crystallographic orientation affect corrosion resistance?

As shown in Figure 5

1 (c), a clear relationship between the corrosion resistance and the crystallographic orientation exists, and this agreed with earlier data from the literature that the corrosion resistance of Mg alloys increases with increased intensity of basal texture

How does crystallographic orientation affect tribological performance of Ag solid lubricant?

The crystallographic slip plane of Ag became parallel to sliding direction by mechanical rubbing motion

The crystallographic orientation of the Ag solid lubricant layer with nanometric thickness had a strong effect on its tribological performance

What is crystallographic orientation?

The orientation of a crystal can be described by a rotation that transforms it into some standard position

Because crystals tend to be symmetrical, this rotation is known only up to multiplication by an element of the symmetry group

The first part of this paper summarises the embedding approach to studying crystallographic orientations
