The as-cast γ' morphology is shown in Fig. 1.
The incipient melting point and the heat treatment process is indicated in Table 1.
If the cuboidal γ' is forced to obtain, its edge length will exceed 1µm causing adverse effect on mechanical properties.

The dike in the tank area is about 40meters long and 10 meters wide, 1 meter high, with the cover area of approximately 400m2.

In [4] is presented a comparative analysis for two wheels profiles (ISO 1395-1977 and ANSI ASA B29.1-1950) for a bush chain transmission.
By considering z = 60, the wheel’s profile geometrical parameters are determined (figure 1).
Table 1 presents the numerical values of the wheel’s geometry.

The bed, once the reaction completed, was ground in a jaw crushed and sieved through a sieve with 1 mm sieve mesh.
After 15 days (360 h), the compacts were sintered at 1,750°C for 1 min in nitrogen flow.
