Thèse confidentielle jusqu'au 05 avril 2011The copper-beryllium alloys characterized by a structural hardening present mechanical properties close to those of high steels (Rm#1230MPa, Re 0.2#1060MPa, A%#6.5). On the other hand, they present high thermal and electric conductivities (22%I.A.C.S), a good resistance to wear and to corrosion, and they are non magnetic. The conjugation of these different properties enables Cu-Be alloys to find a broad range of applications (brake discs for planes, welding electrodes, spring Bumblebee for manometer etc). However, in addition to the cost raised by béryllium, the main inconvenience of these alloys is the presence of the beryllium oxide that is harmful when it is inhaled as powder or fume. In spite o...
