Figure 6
An S E M image with marked spectrum points shows aluminium copper alloy regions. Associated E D S spectra confirm aluminium and copper as dominant elements with varying ratios across points.An S E M image highlights selected spectrum points for analysis of aluminium copper alloy. The E D S spectrum at spectrum 5 shows aluminium 90.5 percent and copper 9.5 percent. Spectrum 6 shows aluminium 86.0 percent and copper 14.0 percent. Spectrum 7 shows aluminium 90.4 percent and copper 9.6 percent. The graphs indicate peaks corresponding to aluminium and copper, confirming alloy composition with slight variations among analysed regions.

(a) SEM image of Aluminium 2024-RAM2C after Type 2 post-treatment. EDX results are shown through Spectrum 5 (b), Spectrum 6 (c) and Spectrum 7 (d). The image was taken with the SEM - Tescan VEGA3 (magnification: 5,360Ă—) and the chemical analysis using the embedded EDX
