Borges et al. [5] tested 13 reinforced concrete (RC) flat slabs, each with a thickness of 200 mm and EL-Shafiey [6] tested 7 slab specimens, each with a thickness of 150 mm, along with one reference slab, six slabs with square openings of different dimensions located at the vicinity of the column.
Oliveira et al. [7] tested 7 slab specimens with openings and asymmetrical loading.
Ha et al. [8] and Liberati et al. [9] investigated the effect of small circular openings in the vicinity of the column.

Abstract.
To improve the mechanical properties of AlCuFe alloys, the different dopes are applied.
Doping of Al-Fe alloys with tungsten causes significant increase in yield strength and creep resistance at elevated temperatures of 600°C [7].
The aim of this study was to obtain multiphase Al-Cu-Fe alloy doped with tungsten and to investigate its microstructure.
