This study focuses on effects of the reinforced particles on the physical properties of W
alloys. Different strengthening processes for W-based materials, including the manufacturing …

The WxTaTiVCr high-entropy alloy with 32at.% of tungsten (W) and its derivative alloys with
42 to 90at.% of W with in-situ TiC were prepared via the mixing of elemental W, Ta, Ti, V and …

Yttria dispersion-strengthened tungsten with both enhanced strength and ductility was
synthesized through sol–gel method followed by sintering and high-temperature swaging …

Tungsten is the major candidate material for the armour of plasma facing components in
future fusion devices. To overcome the intrinsic brittleness of tungsten, which strongly limits …

Dense W, W–1wt% La2O3 and W–1wt% Y2O3 samples with fine microstructure were

The effects of rare earth elements (Y 2 O 3, Y and La) on the consolidation behavior,
microstructure and mechanical properties of tungsten alloys were investigated in this work …

The physical properties of tungsten such as the high melting point of 3420° C, the high
strength and thermal conductivity, the low thermal expansion and low erosion rate make this …

Abstract Pure W, W–0.2 wt% Zr (WZ), and W–0.2 wt% Zr–1.0 wt% Y 2 O 3 (WZY) with a
relative density of above 97% were fabricated by spark-plasma-sintering method. The …

In this work, the effect of three different oxide dispersoids (Y 2 O 3, La 2 O 3, ZrO 2) addition
on densification, phase, microstructure evolution and high-temperature stability has been …

In this study, tungsten heavy alloys reinforced with highly uniform and dispersed nanosized
Zr (Y) O 2 particles were investigated. These alloys exhibited a high compressive strength …
