Abstract：

Conventional　fabrication　methods　for　W[sbnd]Cu　composites　possess　several　limitations　on　the　ultimate　densification　and　comprehensive　performance　of　products.　Here　we　propose　an　innovative　protocol　to　prepare　W[sbnd]Cu　via　photochemical　reactions　at　ambient　conditions.　Specifically　engineered　polymeric　reagent　guided　the　continuous　growth　of　Cu　within　W　matrix　and　enhanced　the　affinity　among　W/Cu　phases,　whose　combination　led　to　well　densified　W[sbnd]Cu　composite.　Our　strategy　completely　avoided　thermally　induced　grain　growth　and　flipped　the　immiscible　nature　of　W/Cu　interfaces.　It　was　even　possible　to　simultaneously　fabricate　and　shape　products　using　patterned　light　field.　This　strategy　provides　new　insight　on　fabricating　metallic　composites.　©　2025　Elsevier　Ltd
