Notes
  • PLT and Doppler broadening S-parameter were used for AlâMg alloy, namely 5005, 5051, 5052 and 5083. The trapping efficiency was estimated for the pervious alloys as 2.42 Ã 109, 2.29 Ã 109, 2.24 Ã 109 and 2.27 Ã 109 s-1 cm3, respectively and the trapping cross-section was estimated to be as 2.66 Ã 10-16, 2.14 Ã 10-16, 2.10 Ã 10-16 and 3.51 Ã 10-16 cm2, respectively. It is clear that the mean lifetime and S-parameter have the same behavior as a function of deformation degree and saturated at the same value of thickness reduction.
