  • Penetrator incorporating a core enclosed in a ductile sheath and manufacturing process for such a penetrator
    Patent number: 10240906
    Abstract: A heavy metal penetrator with a high tungsten content incorporating a central part or core formed of an alloy comprising from 85% to 97% in mass of tungsten associated with additional metals and which is enclosed by a peripheral sheath made of a more ductile tungsten alloy than that of the core. The sheath of the penetrator is made of an alloy comprising 30% to 72% in mass of tungsten, the core comprising nodules of tungsten bound in a matrix of a gamma phase ?C associating tungsten with additional metals, the two gamma phases being continuously joined to one another with no transition zone.
    Type: Grant
