However, the purity of aluminum step-wedges should be at least 98% (mass fraction) and the radiopacity should not be less than 0.5 mm Al of any value claimed by the manufacturer.

The following phases occur in the Zn-Al binary diagram [1]: α - Al-rich phase (lattice K12), α´ - matrix rich in Al in equilibrium with α´m, α´m - second transition phase, β - phase rich in Zn (lattice K12), η - phase rich in Zn (lattice H12).
In paper [5], Zn-based alloys with 4 – 6 % Al at 3 % Cu were analysed.
This trend was also confirmed in the work [4] for three levels of Al, namely 8, 12 and 27 %.
The authors attribute this to the replacement of η dendrites rich in Zn by α phase, rich in Al, and increasing the amount of α + η eutectoid with an increase in the content of Al from 8 to 27 %.

Guo et al. [15] found that SW defects can cause a significant increase in friction force and energy dissipation rate between the atomic smooth layers.
Recently, Liu et al. [16] reported that the existence of defects like vacancy and SW were found to increase the energy dissipation rate and rocking motion, thus enhancing the probability of oscillation failure.
Kis et al. [17] experimentally measured the inter-tube force of DWCNTs inside a TEM.

Bray et al. have shown that prior corrosion pitting reduced the fatigue strength of aluminium alloys 2024-T3 and 2524-T3 by approximately 40% [10].
Sankaran, et al. [5] used modelling approach to quantitatively account for the effects of prior corrosion on the fatigue behaviour of 7075 T6 Aluminium alloys.
