Abstract

Powder metallurgy is widely used in technical practice to manufacture products with specific properties. In the field of ammunition, powder metallurgy technology is used to produce frangible bullets designed for fire arms.This paper presents results of pressing of experimental cylindrical samples from mixture of Fe – Sn metal powders. The samples with the diameter of 9 mm were compacted by cold pressing in cylindrical rigid die without additional sintering. By changing the axial pressing force in the range of 10 to 40 kN various physical and mechanical properties of the produced samples were achieved. The determined mechanical properties of manufactured specimens are an important input for the further development of pistol frangible bullets of 9 mm calibre.

Keywords: Powder metallurgy, mixture powder Fe-Sn, frangible bullet, green density, green strength
