Definition for Particle Size

2011-06-01
CURRENT
J391_201106
"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.

Definitions for Macrostrain and Microstrain

2011-08-04
CURRENT
J932_201108
In the analysis and measurement of residual stresses of materials, it has been noted that there are frequently differences in interpretation of the terms "macrostrain" and "microstrain." To assist communication among research personnel in this area, definitions for these two terms are suggested by the Fatigue Design and Evaluation Committee of SAE. Since "macrostress" is commonly computed from "macrostrain" in residual stress analysis, to be consistent, the definitions given are for "macrostrain" and "microstrain."
