The preponderant parameters, given
the specific red-orange colour of these potteries, are: the size (submicrometric), the composition (Ti
and Al-substitutions) and the density of hematite crystals in the aluminosilicate amorphous matrix
forming the slip [17].

According to a model
proposed by Jedlinski and al [16], the fine dispersion of yttria and the presence of TiC in the ODS
alloy provide nucleation sites for heterogeneous nucleation of chromia and consequently α alumina
grains.

Therefore, most Al alloys require aging process to further improve their mechanical properties.
Fig.1 The result of simulation of multi-component Al alloys: the first is the initial stage and the others are final stage in different alloys (a)initial stage (b)Al-Zr (c)Al-Fe (d)Al-Zr-Li (e)Al-Zr-Mg (f)Al-Cr-Fe (g)Al-Zr-Cr-Fe-Ti (h)Al-Zr-Mg-Ti-Mn-Fe-Li-Ni (i) Al-Zr-Li-Si-Mg-Mn-Ti-Cr-Fe-Ni Fig.1 exhibits the simulation results for binary and multi-component Al alloys, the numbers in the figure represent element numbers.
Peng et al.[17] also discovered that Zr in Al alloys are more likely to form cluster structures.
Fig.1(d) shows the results for the Al-Li-Zr alloy, fig.1(e) is Al-Mg-Zr alloys and fig.1(f) is Al-Cr-Fe alloy after MC simulations.
