“…Nickel, used as the basic alloy component forming the binding phase (matrix) of WHA alloys, lowers the sintering temperature and ensures the good wettability of tungsten grains and its solubility in the liquid phase. The other ingredients, i.e., Fe, Cu, Co, and others, function to lower the sintering temperature, reduce the solubility of tungsten in nickel, improve the mechanical properties of the matrix, and increase the strength at the interface between the tungsten grain and the matrix phase [ 22 ]. In order to reduce the oxides, the sintering process is carried out under a hydrogen atmosphere.…”

The paper presents the results of studies on the effects of heat treatment and cold-work parameters on the mechanical properties and microstructure of the tungsten heavy alloy (WHA) with the composition W91-6Ni-3Co. Tungsten heavy alloy (WHA) is used in conditions where strength, high density, and weight are required. The material for testing as rod-shaped samples was produced by the method of powder metallurgy and sintering with the participation of the liquid phase and then subjected to heat treatment and cold swaging. The study compares the effect of degree deformation on the strength, hardness, microhardness, and microstructure of WHA rods. The conducted tests showed that heat treatment and cold-work allowed to gradually increase the strength parameters, i.e., tensile strength σuts, yield strength σys, elongation ε, hardness, and microhardness. These processes made it possible to increase the tensile strength by over 800 MPa (from the initial 600 MPa after sintering to the final value of over 1470 MPa after heat treatment with cold swaging deformation with reduction of 30%) and the hardness from 32 to 46 HRC.

“…A new tungsten fiber/Zr alloy metallic glass matrix composite [14][15] armor-piercing core was studied by Dewu Huang and Rongguang et al The depth of penetration of the tungsten fiber composite core was about 72% greater than that of the tungsten alloy core for similar bullet weight, bullet shape, charge, muzzle velocity, and angle of impact. [7] Jicheng Li [44] and others studied the ballistic performance of tungsten particle/metallic glass-based composite long rods. Eva Liden [45] conducted a study on the fragmentation propensity of long rod ammunition It has been claimed that tungsten heavy alloy (WHA) rods exhibit "self-sharpening" behavior when shaped using severe plastic deformation methods.…”

In this paper, the armor piercing power of 93W-4Ni-3Fe and 88WC-12Co with the same target velocity and core size is compared through experiments. The craters formed by the penetration of the same size projectile core made of 88WC-12Co and 93W-4Ni-3Fe into the semi-infinite Q235 steel target at the velocity of 1300 m/s–1500 m/s were compared. The penetration depth of 88WC-12Co is 12.5% –35% lower than that of 93W-4Ni-3Fe ( including residual projectile core ), and the pore size is about 12%–26% smaller. At the velocity of 1300 m/s-1480 m/s, there are more residual projectiles at the bottom of 93 W projectile pit. When the velocity is higher than 1510 m/s, the residue is less and the utilization rate of core material is higher. The aperture caused by the penetration of 88WC-12Co projectile core is slender and smooth, and the residual at the bottom of the crater is less than 93W. This proves that 88WC-12Co material has certain armor piercing self-sharpness. It is speculated that 88WC has a similar or even higher penetration ability to 93W when the initial kinetic energy of the two cores is the same.

“…Owing to the absence of long-range orders in their atomic structure, metallic glasses (MGs) exhibit fascinating mechanical properties such as high elastic limit, superior strength, and good self-sharpening [1][2][3][4]. Recently, MGs have been also identi ed as the promising materials for high-velocity impact applications, in which their shock responses grew in considerable importance [5][6][7][8][9].…”

In this work, the shock wave response of a pore-embedded CuZr metallic glass (PEMG) under different impact velocities (0.5–1.5 km/s) and initial temperatures (300–600 K) was evaluated through the molecular dynamics (MD) simulation. The results indicated that the nucleation and growth of nanoscale shear events around the pore were the dominant mechanisms for plastic deformation under the shock wave. It was also found that the increase in the impact velocity led to the filling of pore, which was due to the structural softening and the local temperature increment in the vicinity of pore. Moreover, the spall event originated from the formation and coalescence of tension transformation zones, leading to the formation of nanovoids in the system. At higher velocities, the spallation was accompanied with the formation of more nanovoids with smaller sizes, inducing the brittle failure in the system. The MD outcomes also showed that the increase in initial temperature decreased the shock pressure and flow shear stress and led to the smoother spallation in the PEMG.
