Tungsten alloy swaging rod grades under transient high heat loads
Transient high heat loads simulations by using the electron beam facility have been performed on two tungsten alloy swaging rod grades at several power loads with a pulse duration of 5 ms. The cracking patterns of the two tungsten alloy swaging rod grades are quite similar. All cracks occurred along the grain boundary and located across the loaded area. The cracks can be distinguished with two levels, major cracks with larger crack width but lower crack density and microcracks with smaller crack width but higher crack density. The higher the deformation level of tungsten alloy swaging rod and heat loading power density, the smaller the major crack density will be, but there is no obvious difference in the microcracks pattern. No melting occurred for both tungsten alloy swaging rod grades after transient heat loading at power density of 0.88 GW m−2.

Types of tungsten alloy armor piercing projectile introduction
Tungsten alloy armor piercing projectile comprising a high density penetrator core with a tapered front end and a multi-part outer case in partial contact with the core. This kind of tungsten alloy armor piercing projectile will not penetrate because the multi-part jointed case is not as strong as a single-piece, monolithic case. Also, since the hard core is loose and not bonded to the case, then the core can not provide additional structural support. In addition, the tungsten alloy armor piercing projectile does not have the ability to either explosively damage the target after penetration, or take data from an instrumentation package during or after penetration.
Tungsten alloy armor piercing projectile comprising an axial core, a continuous strip of metallic glass wound about said core, and bonding means for joining the adjacent laminated surfaces. It describes an outer case with a hole at its tip. This "hollow-point" design results in radial expansion of the jacket into "petals" as the tungsten alloy armor piercing projectile travels through the target. Such "flowering" of the case upon impact severely limits the depth of penetration into hardened targets.
Tungsten alloy armor piercing projectile comprising a heavy metal core and a segmented sabot with both right-handed and left-handed threads that separates from the core after exiting the gun's nozzle. This tungsten alloy armor piercing projectile will not penetrate deeply because the nose end is made of a brittle heavy metal alloy, rather than high-strength steel. Also, this tungsten alloy armor piercing projectile requires the use of a discarding sabot carrier.
Tungsten alloy armor piercing projectile with a speculating core comprising an elongated arrow style tungsten alloy armor piercing projectile with a core surrounded by a body, where the hardness of the core is greater than twice the hardness of the body. The outer case is made out of a heavy metal alloy. The brittle behavior of these alloys will prevent this tungsten alloy armor piercing projectile from achieving deep penetration in hardened targets, when compared to cases made of high-strength and high-toughness steel alloys.
