Abstract (en)

[origin: WO2017013314A1] The invention relates to a heavy metal penetrator (3) having a high content of tungsten comprising a central portion or core (7) formed from an alloy comprising from 85% to 97% by weight of tungsten combined with additional metals and which is surrounded by a peripheral sheath (8) of a tungsten alloy that is more ductile than the material of the core. The sheath (8) is made from an alloy comprising from 30% to 72% by weight of tungsten, the core (7) comprising tungsten nodules bound by a matrix of a Yc gamma phase combining the tungsten with the additional metals, the two gamma phases being joined to one another continuously with no transition zone. Another subject of the invention is a process for manufacturing such a penetrator.
