crystal grain

This problem is due to crystal grain boundaries in the material.

The synthetic version is a powder and yields only small crystal grains with poor structure.

First, the random orientation of the crystal grains makes it difficult to choose a value for the linear rate constant.

The crystal grains in the air formed a reflective curtain which threw back our tracking beams.

This change was expected to produce larger crystal grains and thereby increase the inherent strength of the metal filament.

It includes a class of hard minerals occurring as lath- or plate-shaped crystal grains.

This led to his interest in preferred orientations in the crystal grains that compose a metal object.

Small-angle laser light scattering has provided information about spatial density fluctuations or the shape of growing crystal grains.

The boundary between one crystal and the next can easily be traced and the various crystal grains distinguished from each other.

He leaped up and started in pursuit, only to be arrested by a flash of purest blue among the crystal grains of sand.

Crystal grain sugar was the product of Manila which was exported primarily to Spain.

In the first, the magma is cooled slowly deep in the crust, creating the large crystal grains with a diameter of 2 mm or more.

The above image shows loose crystal grains in dark matrix from a thin section of Vaca Muerta meteorite.

Below the Curie point temperature, the high dielectric constant prevents the formation of potential barriers between the crystal grains, leading to a low resistance.

In a TEM, a single crystal grain or particle may be selected for the diffraction experiments.

But it is possible to fabricate metals that have a nonuniform structure, with very small crystal grains, or regions of different phase or orientation.

They clambered into the mantid, bringing more crystal grains that winked in polychromatic glory whenever the sunlight caught them.

The very idea that crystal grain boundaries could migrate within a solid metal has been extensively studied within the last decade, Demkowicz says.

For those who like a little grain flavour, steep do not boil about 200 grams of crystal grain for 1 hour strain and sparge.

Further drawing will cause the crystal grains to elongate and reorient in the direction of the tensile axis, further strengthening the fibers.

When viewed in cross section, the lenticular (lens-shaped) crystal grains are sometimes incorrectly described as acicular (needle-shaped).

Then, the researchers concentrated on making the individual crystal grains span the entire small-scale structure, removing the crystal-grain boundaries where cracks are most likely to occur.

The material failures were found to result from very large grain sizes in the composites and pure ceramics, with cracks following macroscopic crystal grain boundaries.

When metals are be made to cool with the same internal structure as a glass and without crystal grain boundaries, they are less likely to fail, Royall said.

Some of Sir Charles' ideas relate to 19th-century physics such as his very recent work on the vectorial description of the rational relationships between neighbouring crystal grains.
