Abstract
Doppler broadening is a sensitive non-destructive nuclear technique used to detect mechanical working in the form of deformation effect.To distinguish between valence and core electrons of wrought 5xxx Al-alloys, Doppler broadening line-shape (S and W parameters)have been measured. The effect of the degree of deformation on these parameters has been carried out usingdifferent (5052, 5251 and 5754) Al-Mg alloys samples.An exponential increase in the S-parameter accompanied with an exponential decrease in the W-parameter with increasing the degree of deformation was observed before reaching saturation for both of them. The linearity in the S- versus W-parameters for the investigated (5251, 5052, and 5754) Al-alloys has been used to identify the defect type.
