Ultrahigh transverse rupture strength in tungsten-based nanocomposites with minimal lattice misfit and dual microstructure

New-generation structural materials with superior properties are a constant demand in applications involving extreme environments. Here, we demonstrate the fabrication of a high-strength, high-dense W-TaC-Ta2O5 nanocomposite for such applications on a large scale by a simple, cost-effective, scalabl...
