Aluminium schematic diagrams illustrating

Schematic diagram illustrating the growth process of the AlSb layer at the aluminium-antimony interface is shown in Fig. 1.13. The kinetics of interaction in this system have been studied by B.Ya. Pines and E.F. Chaikovskiy144 (see also Ref. 9) using X-ray patterns obtained from the rotating cross-sections of the aluminium foil, 15 pm thick + polished antimony disc, 3-4 mm high specimens in a cylindrical self-focusing chamber.

Both intermetallic compound layers, Al3Mg2 and Al Mgn, were found to grow simultaneously at the interface between aluminium and magnesium. A schematic diagram to illustrate their growth process is shown in Fig. 2.16a, while the microstructure of the Al-Mg transition zone in Fig. 2.16b.

At the same time, a similar system was developed with the specific aim of performing thermogravimetric (TG) experiments during the microwave pyrolysis of plastics and plastic/aluminium laminates [26]. The schematic diagram of the apparatus developed is illustrated in Figure 21.2.
