Resumen
In this work, a study of the crystalline perfection of an aluminium single crystal
is presented. The study shows that, from three-dimensional neutron diffraction
rocking curves, it is possible to characterize the individual crystalline domains of a multidomain crystal. From a macroscopic point of view, the determination of the domains allows an evaluation of the crystalline perfection of the crystal
under study. Three-dimensional rocking curves have been obtained by neutron
diffraction from a large mosaic aluminium crystal. Construction of a contour
map of individual domains made it easier to determine the breadth and relative
intensity of each domain. The angular distances between domains were also
determined.
