Achieving high strength and ductility in ODS-W alloy by employing oxide@W core-shell nanopowder as precursor

Abstract

Aggregation and coarsening of the second-phase oxide particles at grain boundaries have been a bottleneck for improving mechanical properties of oxide-dispersion-strengthened (ODS) alloys. Here the authors employ core-shell nanopowder precursors to achieve uniform dispersion of oxides in ODS alloys.
