Ceramography - Ceramographic Analysis
... thin sections, where the contrast between grains comes from birefringence ... analyses of microstructures are grain size, second-phase content and porosity ... Grain size can be measured by the line-fraction or area-fraction methods of ASTM E112 ...
Strengthening Mechanisms Of Materials - Strengthening Mechanisms in Metals - Grain Boundary Strengthening
... In a polycrystalline metal, grain size has a tremendous influence on the mechanical properties ... Because grains usually have varying crystallographic orientations, grain boundaries arise ... Grain boundaries act as an impediment to dislocation motion for the following two reasons 1 ...
Sedimentary Rock - Properties - Texture
... The size, form and orientation of clasts or minerals in a rock is called its texture ... The size and form of clasts can be used to determine the velocity and direction of current in the sedimentary environment where the rock was formed fine ... The grain size of a rock is usually expressed with the Wentworth scale, though alternative scales are used sometimes ...
Grain Boundary Strengthening - Theory
... In grain-boundary strengthening the grain boundaries act as pinning points impeding further dislocation propagation ... Since the lattice structure of adjacent grains differs in orientation, it requires more energy for a dislocation to change directions and move into the adjacent grain ... The grain boundary is also much more disordered than inside the grain, which also prevents the dislocations from moving in a continuous slip plane ...

Famous quotes containing the words size and/or grain:

    Delusions that shrink to the size of a woman’s glove,
    Then sicken inclusively outwards:
    . . . the incessant recital
    Intoned by reality, larded with technical terms,
    Each one double-yolked with meaning and meaning’s rebuttal:
    For the skirl of that bulletin unpicks the world like a knot....
    Philip Larkin (1922–1986)

    A true politeness does not result from any hasty and artificial polishing, it is true, but grows naturally in characters of the right grain and quality, through a long fronting of men and events, and rubbing on good and bad fortune.
    Henry David Thoreau (1817–1862)
