Investigation of the technology of bronze production by the powder metallurgy method

Summary

• 1. The investigation described has demonstrated the feasibility of preparation of sintered bronzes containing aluminum, manganese, iron, and silicon as alloying elements, using powder metallurgy methods with the introduction of the alloying additions in the form of powders of pure elements or addition alloys.

• 2. Double compacting at pressures of 10–12 · 10⁹ N/m² yields material with a final porosity of 4–6%.

• 3. The optimum sintering temperatures for bronzes of the compositions investigated range between 1173 and 1223°K.

• 4. By employing the procedure described for the preparation of sintered bronzes, it is possible to obtain relatively stable and homogeneous structures, the phase composition of which is determined by the phase diagrams of systems of the elements contained in these sintered bronzes.
