Phase, microstructure and properties evolution of fine-grained W–Mo–Ni–Fe alloy during spark plasma sintering

Fabrication, characterization, and mechanical properties of 93W–4.9Ni–2.1Fe/95W–2.8Ni–1.2Fe–1Al2O3 heavy alloy composites

“…However, WHAs exhibit 10-20% lower penetration performances than DUAs at high strain rate [3,4]. Therefore, significant efforts have recently been devoted to improve the performance of W-Ni-Fe heavy alloy penetrators, including alloying element addition [5][6][7], microstructure refinement [7][8][9][10], and deformation strengthening [11][12][13].…”

Tungsten Heavy Alloys with Molybdenum, Y2O3 and Lanthanum. A Review

“…Powders of W, Mo, Ni, and Fe with purity higher than 99.5 % and particle size is around 1-3 microns. The powders were blended at a mass proportion of 88:2:7:3 (W:Mo:Ni:Fe) [25]. QM-2SP20 planetary high energy ball mill is utilized in which tungsten powder is set where the ball to powder weight proportion of 5:1 is kept up and a WC cemented carbide ball was utilized as the pounding media [25].…”

As W and Mo are components of the same VIA gathering, their lattice parameters are close which empowers the blending procedure easily.…”

“…As W and Mo are components of the same VIA gathering, their lattice parameters are close which empowers the blending procedure easily. Mo which is commercial and non-radioactive, decreases the dissolving point by which the refinement of grains in compound happens [25]. Figure 2 shows the sintering temperature impact on the relative thickness of the W-2Mo-7Ni-3Fe combination utilizing the HEBM in SPS method.…”

“…The grain development system of WHAs with various measures of Molybdenum are studied by Hsu [28] It is obvious from the Fig. 3 that the intensity of diffraction pinnacle of W rises with increase in temperature [25]. It is likewise seen that there is no critical change in the diffraction top width with a rise in temperature.…”
