In　this　work,　accelerated　sintering　of　Y2O3　dispersion　strengthened　tungsten　alloy　with　a　well-regulated　structure　was　achieved　by　a　novel　dissolution-precipitation　strategy.　As　indicated,　yttrium　oxide　was　firstly　dissolved　into　the　lattices　of　W　powder　precursor　during　the　thermal　plasma　synthesis　process　in　a　one-step　and　ultra-fast　way,　and　then　homogeneously　precipitated　out　within　W　grains　during　sintering.　The　theoretical　calculation　reveals　that　the　formation　process　of　Y2O3　dispersoids　enhanced　the　driving　force　of　densification　by　increasing　the　sintering　stress　and　declining　the　macroscopic　viscosity,　resulting　in　improved　diffusion　ability　for　the　W　skeleton.　The　microstructural　investigation　further　confirmed　the　occurrence　of　mass　inter-diffusion　at　the　W-Y2O3　interface,　which　provides　a　fast　diffusion　pathway　for　W　atoms,　and　is　responsible　for　the　accelerated　densification　kinetics.　Being　sintered　at　1600　°C　for　1　h,　the　as-obtained　alloy　possesses　a　high　relative　density　of　98.26%,　together　with　a　refined　grain　size　of　970　nm　for　W　and　50　nm　for　intragranular　Y2O3,　respectively.　©　2023
