Abstract：

A　novel　multistage　aging　heat-treatment　method　was　applied　to　investigate　the　microstructural　evolution　and　properties　of　an　additive-manufactured　2319　aluminum　alloy.　The　microstructure　and　mechanical　properties　were　analyzed,　and　the　results　revealed　that　the　as-built　annular-shaped　components　were　characterized　by　an　alternating　distribution　of　thin　equiaxed　crystals,　dendrites,　and　coarse　columnar　crystals.　The　microstructure　occurs　recrystallization　and　the　average　grain　size　decreased　after　the　two-stage　aging　treatment.　The　maximum　texture　strength　in　the　selected　area　increased　after　the　two-stage　aging　treatment,　and　the　angle　grain　boundaries　were　evenly　distributed.　Solid　solution　plus　aging　could　significantly　improve　ultimate　tensile　strength　and　hardness.　The　tensile　fracture　morphology　was　typical　of　ductile　fracture.　Two-stage　aging　exhibited　a　higher　corrosion　resistance.　©　2023　Elsevier　Ltd
