Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving …

Tungsten is a refractory metal with the highest melting temperature and density of all metals
in this group. These properties, together with the high thermal conductivity and strength …

Nickel-tungsten-yttrium oxide (Ni-WY 2 O 3) composite coatings were co-electrodeposited
onto low-carbon steel surfaces using the direct current electrodeposition method with a …

In this study, Ni–W nanocrystalline alloy coatings incorporated with different amounts of Y 2
O 3 nanoparticles (0–20 g/L in the electrolyte) were successfully synthesized via direct …

In this study, we evaluated the influence of a new mechanical nanostructuring technique
called High Pressure Torsion Extrusion (HPTE) on the microstructural evolution of niobium …

Tungsten heavy alloys are two-phase metal matrix composites that include W–Ni–Fe and W–
Ni–Cu. The significant feature of these alloys is their ability to acquire both strength and …

The intrinsic brittleness of tungsten limits the improvement on the comprehensive
mechanical properties of tungsten alloys. Starting from the perspective of solid solution …

In the current study, the reduced graphene oxide (rGO) was introduced into W-Cu
composites for in-situ formation of WC particles using one-step thermal reduction and …

Due to the importance of wear behavior in tungsten base alloys, this issue has rarely been
considered. The present study deal with the effect of Y 2 O 3, its amount and sintering on the …

W alloys prepared via oxide dispersion strengthening have shown enhanced mechanical
performance. In this paper, W-1.10 vol% Zr-2.00 vol% Y 2 O 3 (WZY) and W-1.10 vol% Zr …
