The values of lattice spacing, d, obtained were matched with phases based on Al, Mg, Al-Mg, Mg-O and Al-O systems.
Smooth bar tensile properties of the extruded Al-Mg and Al-Mg/Al2O3 samples were determined in accordance with ASTM test method E8M-96.
Table 1 Density, porosity and tensile properties of Al-Mg and Al-Mg/Al2O3 samples.

Nagao et al. [12] established that Ca reduces Bi impurities in Al-5% Cu alloy melts through the formation of Bi3Ca5.
Strontium was added in the form of Al-10%Sr master alloy, while magnesium was added as pure metal.
Trace additions of Bi and Ca were made using Al-5%Bi and Al-10%Ca master alloys (see Table 1 for actual levels obtained).

Mori et al. [4] enclosed the spinning setup in a chamber and used hot air to heat cast aluminium blank.
Davidson et al. [5] found the depth of cut, the feed, the starting dimension of the preform, the starting heat treatment condition of the preform and the speed of the mandrel had significant role in the quality of the final product.
To analyze the forming characteristics and laws of hot splitting spinning process of magnesium alloy AZ31, Yang et al. [6] established a 3D elastic–plastic FE model of hot splitting spinning process.

Eight pieces of pure Al (99%) sheets and seven pieces of pure Fe (99.5%) sheets were mutually stacked so that the overall composition was Al-55at%Fe.
Although amorphous phase was found, the smallest halo ring is located at the inside of the Al (111) ring that is the strongest diffraction of Al.
If the amorphous phase formed from Al matrix (Al-Fe solid solution), the smallest halo ring should be normally located at the outside of Al (111) ring.
(2) Fe dissolved into Al during the ARB of Al/Fe multilayered to form Al-Fe supersaturated solid solution.
