Description / Abstract:
"Effective particle or domain size " is a phrase used in X-ray
diffraction literature to describe the size of the coherent regions
within a material which are diffracting. Coherency in this sense
means diffracting as a unit. Small particle size causes X-ray line
broadening and as such can be measured. It has been shown related
to substructure as observed in transmission electron microscopy.
Particle size is affected by hardening, cold working, and fatigue;
conversely, there is increasing evidence that particle size, per
se, affects both static and dynamic strength.
