Microstructure and sintering behavior of nanostructured W-10–20 wt.% Ti alloys synthesized by a soft chemical approach

•W-10–20 wt.% Ti nanoalloys with average particle sizes ~ 50 nm were synthesized.•The amorphous as-synthesized W–Ti powders, when annealed at 600 °C, resulted in the formation of bcc tungsten and hcp titanium.•Relative densities of 98.4 to 99.1% were achieved for W–Ti alloys on sintering.•Superior mechanical properties were also achieved in W–Ti sintered compacts.

The present work reports a soft chemical approach for synthesis of nanostructured W 10–20 wt.% Ti alloys and its characterization. Though, the as-prepared products are amorphous, they developed crystalline phases when annealed at 600 °C due to the presence of bcc and hcp structure of W and Ti respectively. ESEM and TEM studies show that the sizes of as-synthesized powders ranged between 30 and 50 nm. W-10–20 wt.% Ti alloys, when sintered at 1400 °C for 1 h, exhibit relative density, Vickers hardness and electrical resistivity varying between 98.4–99.1%, 506–595 Hv and 6.28–7.43 μΩ-cm respectively.
