To minimize the porosity due to Kirkendall diffusion and refine the microstructure of the synthesized γ-TiAl alloys, nanocrystalline Ti/Al (atomic ratio 1:1) composite powders as a precursor for synthesis of γ-TiAl alloy were prepared by mechanical milling [19, 20].

The incorporation of wastes from various industrial activities in ceramic products appears as a technological alternative to reduce the environmental impacts caused by the indiscriminate disposal of wastes in nature [1, 2].
Results and Discussion Particle size analysis Table 1- Particle size analysis of the green ceramic mass particles Composition Clay (%) (x<2µm) Silt (%) (2µm< x <20µm) Sand (%) (x>20µm) Diameter Average (µm) Composition: (35%) de R.Kaolin; (35%) R.
Thermogravimetric analysis: Figure 1 illustrates the thermogravimetric analysis curve of the ceramic mass Fig. 1 – Thermogravimetric analysis of the ceramic mass In the thermogravimetric analysis curve, it is observed three stages of mass loss.
The second stage is between 225 and 479oC, and can probably be associated to the organic matter and hydroxyls of the clay fraction and the third and last stage between 479 and 690 oC, can be related to the decomposition and loss of carbonates and hydroxides present in the ceramic mass.

Fig.1 Variation of hardness of Cu-0.6%Cr-0.15%Zr-0.05%Mg-0.02%Si alloy with aging time and temperature (a) rolling 50% (b) rolling 80% Fig.1 also shows the effect of the amount of rolling on hardness of Cu-0.6Cr-0.15Zr-0.05Mg-0.02Si alloy.
After 80% rolling and aging at 480˚C for 1 h, the electrical conductivity is 85.5% IACS as shown in Fig. 2.
Conclusions (1) Cu-0.6%Cr-0.15%Zr-0.05%Mg-0.02%Si alloy can attain good comprehensive properties after 80% rolling and aging at 480˚C for 30min, the hardness and conductivity reach 150HV and 82.5%IACS, respectively.
