3.3 Results The investigation showed that in the system studied, only few phases belonged to the binary and ternary Al subsystems. These phase were Al 2 Cu, AlLi, A1 75 CUJLÌ(TB), Al 2 CuLi(T,), Al 6 CuLi 3 (T 2 ), Al 2 LiMg, Al 2 CuMg(S). Using the results from the experiments three isothermal sections of the phase diagram were constructed: 1. At 400 °C with the amount of 1.5 wt.% Cu 2. At 400 °C with the amount of 2.8 wt.% Cu 3. At 500 °C with the amount of 1.5 wt.% Cu 4. At 500 °C with the amount of 2.8 wt.% Cu. Figure 6 shows the phase boundaries measured at 400 °C. 1. (Al) + S 2. (Al) + S + TB 3. (Al) + S + T B + Τ, 4.
