Definitions
- the technical field of the invention - . is that of the heavy metal penetrators and in particular that of the indenters used to make sub-sized projectiles of large caliber (calibrated greater than or equal to 25 mm).
- projectiles are most often called arrow projectiles. They include a sub-calibrated indenter or bar that is pulled by a weapon using a weapon-sized hoof.
- the indenter For a projectile of 120 mm caliber, the indenter generally has a diameter of 20 to 30 mm and the hoof allowing the firing is formed of a set of sectors of light material (aluminum alloy for example).
- Patents FR-2521717 and FR-2661739 describe examples of arrow projectiles.
- the penetrators are most often made . in an alloy with a high tungsten content.
- Such alloys are sensitive to transverse stresses they receive during impact against a: inclined target or when interacting with a reactive protection.
- the transverse shocks cause the breaking of the penetrator which reduces the piercing power of the indenter after passing such targets.
- penetrators a liner device in a more ductile material ensuring resistance: a bending to the indenter.
- EP-1940574 an indenter comprising an alloy core comprising 90 to 97% by weight of tungsten and which is surrounded by a peripheral sheath of a tungsten alloy more ductile than the material of the heart.
- the sheath of this indenter has a proportion of tungsten between 85% and 91%.
- the tungsten percentage of the sheath is relatively close to that of the core and this penetrator therefore has insufficient flexural strength performance.
- Such an indenter is not adapted to the current needs of producing projectiles arrows having an elongation, ie a ratio (L / D) of the length (L) of the indenter on the diameter (D) of the indenter, which is important.
- patent EP-194 0574 proposes to sinter the core and the sheath in the same mold.
- the separation between sheath and heart is provided by a special funnel associated with a tube that separates the heart zone and the heart . sheath area. After placing materials of the cladding and the heart ', and the tube; the funnel are removed. The sheath and core materials are then in contact and sintering can be performed.
- Such a method has the disadvantage of leaving between sheath and core a " transition zone having a thickness between 25 micrometers and 200 micrometers.
- This zone is formed of a material whose composition and characteristics are intermediate between those of the core.
- the transition zone associates, as well as the core and the sheath, nodules : tungsten and a gamma phase
- the size of the tungsten nodules and the composition of the gamma phase of this zone are obligatorily different from those of the heart and the sheath. If it were otherwise, there would not be such a transition zone.
- this transition zone thickness, positioning with respect to the axis of the indenter .
- the ductility of the sheath obtained with this process is therefore little greater than that of the core, of the order of 5 to 10%. .
- the invention aims to propose a . penetrator structure in which the adhesion between sheath and core is excellent, even with a difference in tungsten content between sheath and core.
- the indenter according to the invention may then have a sheath ductility which. is superior to that of known tungsten sheath indenters.
- the subject of the invention is an indenter : a heavy metal with a high tungsten content, comprising a central part or core formed of an alloy comprising from 85 to 97% by weight of tungsten associated with additional metals and which is surrounded by a peripheral sheath: a tungsten alloy more ductile than the material of the core, indenter characterized in that.
- the sheath is made of an alloy comprising 30% to 72% by weight of tungsten
- heart comprising tungsten nodules bound by a matrix of gamma phase incl combining tungsten with additional metals, the two phases being gamma connected to each other continuously without a transition zone.
- the gamma phases of the core y c and sheath y G will have an associating composition, tungsten, nickel, cobalt and optionally iron.
- the heart may comprise 85% by weight: tungsten and the sheath 38% by weight of tungsten, gamma phases of the heart are c and sheath y G having compositions combining Tungsten, Nickel:: and Cobalt.
- the core may comprise: 89% by weight of tungsten and the sheath 68% by mass of tungsten, the gamma phases of the core y c and sheath y G having compositions combining Tungsten, Nickel and Cobalt .
- the alloy of the core may comprise 95% by weight of tungsten, 2% by weight of nickel, 1.5% by weight of cobalt and 2% by weight of Fe and the sheath 70% by weight.
- tungsten mass, gamma phases of the heart are c and YG sheath having compositions combining tungsten, Nickel, Cobalt and Iron.
- the invention also relates to a method for producing such an indenter.
- the method of manufacturing a heavy metal penetrator high tungsten content is characterized in that it comprises: steps following (which :: lead to the realization of a sketched: this penetrator):
- a sheath composed of compacted powders comprising from 30% to 72% by weight of tungsten combined with additional metals, comprising nickel and cobalt with or without iron,

- the indenter comprises a conical front part 3a and carries at its rear part 3b a stabilizer 4 ensuring its stabilization on trajectory.
- the very structure of the indenter 3 will be described later.
- the shoe wears a belt 5, made of plastic material, which seals the propellant gases when firing into the barrel of a weapon (not shown).
- the propellant charge gases (not shown): exert their thrust at the level of a rear portion 6 of the shoe which is the gauge and which constitutes what is called the thrust plate.
- the shoe 2 .. is intended to allow the shot of the projectile in the weapon. It consists of several segments (most often three) that surround the indenter. 3 and which are in contact two by two at joint planes.
- the segments of the shoe 2 deviate from the penetrator 3 under the action of the aerodynamic pressure exerted on the front portion (AV) of the shoe 2.
- the spacing of the segments leads to the rupture of the belt 5 and the shoe thus releases the penetrator 3 which continues its trajectory.
- Means form concordance (not shown), for example a thread, are interposed between the shoe 2 and the indenter 3 to ensure the drive of the latter.
- FIG. 2 shows more precisely the structure of the indenter 3 which comprises a central part or core 7 which is surrounded by a sheath: peripheral 8.

- the core 7 is formulated to have a yield strength greater than or equal to 1100 MPa (Mega Pascals).
- Ductility is of the order of 6% and a Charpy impact (unnotched test according to ISO 179-1 is' 80 J / cm 2.
- composition of the heart will comprise (proportions in mass): 85 to 97% of tungsten,
- composition of the heart will comprise (proportions by mass):
- the material essentially comprises a matrix 11 of a gamma YG phase essentially associating tungsten with nickel and cobalt with or without Fe, and with a cubic crystalline structure with a centered face which is the sign that this sheath has a high resilience.
- the percentage of tungsten of the sheath 8 is between 30% and 72%, which leads to: a density of this sheath which can vary between 10 g / cm3 and 15 g / cm3.
- the sheath 8 alloy will be formulated to have a ductility greater than 7% and a high resilience: Charpy resilience (non-notched test according to ISO 179-1) greater than or equal to 200 J / cm 2 .
- composition of the sheath will comprise (proportions in mass):
- composition of the sheath include (proportions by weight):

- the gamma phase yc of the heart associates tungsten with nickel and cobalt (with or without iron)
- the gamma YG phase of the cladding will also include nickel and cobalt (with or without iron) as additional metals.
- FIGS. 5a and 5b show that, after forming the penetrator 3, the dies 10 and 11 of the core 8 and of the sheath 7 (matrices formed by the gamma phases of the core and the sheath) are connected to each other. the other continuously without a transition zone.
