The possibility of shock hardening of the weld heat affected zones of 5010 and 6063 aluminum alloys has been studied using a high energy electron beam. The welded samples from both alloys, statically
in 5 seconds, 6mA (current beam) and 10MeV (beam energy) in different dose are irradiated by a non-linear induction accelerator (Rudotron). The results of the hardness measurements exhibit that the maximum hardness in the heat affected zone of 6063 aluminum alloy induced by irradiation of a beam with the dose of 69.99 KGY. Metallorgraphic studies using, SEM, TEM and Image Analyzer showed that shock hardening in samples don't induce hardness??? and the increased hardness values were due to electron beam material interactions.
