Description
Abstract Le bombardement d'un cristal de Ni3Mn ordonné par les électrons du faisceau d'un microscope électronique 1,2 MV entraǐne une mise en désordre partielle de cet alliage. Le degré d'ordre ainsi obtenu dépend de la direction d'irradiation. On donne une méthode permettant de calculer le degré d'ordre pour n'importe queue direction d'irradiation; cette méthode, utilisant la projection stéréographique, tient compte de la focalisation des chocs le long des rangkes ⟨110⟩ du cristal. The bombardment of an ordered Ni3Mn crystal by the beam electrons of a 1,2 MV electron microscope involves this alloy in a partially disordered state. The degree of order thus obtained depends on the direction of irradiation We give a method allowing to calculate the degree of order for any direction of irradiation; this method, using the stereographic projection, takes into account the focalisstion of the collisions along the ⟨110⟩ atomic rows.
