This document describes procedures for measuring average grain size derived from a two-dimensional polished cross-section using electron backscatter diffraction (EBSD). This requires the measurement of orientation, misorientation and pattern quality factor as a function of position in the crystalline specimen[<\/sup> 1<\/sup><\/span>]<\/sup>. The measurements in this document are made on two dimensional sections. The reader should note carefully the definitions used (3.3<\/span>) which draw a distinction between the measured sectional grain sizes, and the mean grain size which can be derived from them that relates to the three dimensional grain size.<\/p>\n

\n
\n NOTE 1\n <\/div>\n

While conventional methods for grain size determination using optical microscopy are well-established, EBSD methods offer a number of advantages over these techniques, including increased spatial resolution and quantitative description of the orientation of the grains.<\/p>\n<\/div>\n

\n
\n NOTE 2\n <\/div>\n

The method also lends itself to the measurement of the grain size of complex materials, for example those with a significant duplex content.<\/p>\n<\/div>\n

\n
\n NOTE 3\n <\/div>\n

The reader is warned to interpret the results with care when attempting to investigate specimens with high levels of deformation.<\/p>\n<\/div>\n
