Two diverse methods to study strained systems of Al-alloy (3004)

The functional targets arising from this study are testing and characterizing cold strained 3004 Al-alloy as it has a good role in energy saving and environmental protection. This alloy was tested and investigated through PALT and XRD technics. The estimated crystallites size and macro strain that were calculated using the XRD approaches are in perfect assent with that obtained from the internal structure and defect computations of PALT. The mean size of crystallites and internal strain values estimated through PALT was slightly smaller with respect to XRD estimated values. The density of faults and dislocations were elevated values in PALT than in XRD. The factors of internal structure for the tested specimens were offered at nearly typical values of the cold distortion state. The results displayed that the distortion operations introduced the size of crystallite, coherent domains, from 0.25 to 0.13 μm by PALT and 0.32 to 0.26 μm by XRD at the same deformation range. Consequently, the internal strain increases from 0.00 to 3.13 × 10-4 by PALT and 4.35 × 10-5 to 5.16 × 10-4 by XRD at the typical deformation range. Finally, the density of dislocations and faults increases from 0.00 to 5.50 × 109 using PALT and 3.30 × 108 to 5.10 × 109 using XRD also through the same calculation ranges.
