Resumen
Six specimens of an aluminum alloy (AA-5083) extruded by Equal Channel Angular Pressing following two different routes plus
a blank sample were examined with a neutron radiation of 1.5448 ˚ A. Macrostrain maps from the (311) reflection were obtained. A
clear difference about accumulated macrostrain with the extrusion cycles between the two routes is shown. The diffraction data of
annealed spec ...

Six specimens of an aluminum alloy (AA-5083) extruded by Equal Channel Angular Pressing following two different routes plus
a blank sample were examined with a neutron radiation of 1.5448 ˚ A. Macrostrain maps from the (311) reflection were obtained. A
clear difference about accumulated macrostrain with the extrusion cycles between the two routes is shown. The diffraction data of
annealed specimens did permit to estimate crystallite sizes that range between 89nm and 115nm depending on the routes. [--]
