Despite　extensive　use　of　ER2319　welding　wires　for　additive　manufacturing　of　aluminum　alloys　in　the　aerospace　and　automotive　field,　the　internal　denseness,　grain　coarseness,　and　non-uniformity　of　additive-manufactured　aluminum　alloy　parts　are　yet　to　be　appropriately　addressed.　Thus,　this　study　attempted　to　overcome　this　gap　by　using　an　ER2319　aluminum　alloy　welding　wire　to　produce　a　uniform　and　fine-grained　aluminum　alloy　using　deformation-based　friction　rolling　additive　manufacturing　(FRAM).　The　findings　demonstrated　that　the　FRAMprepared　materials　were　free　of　voids　and　cracks,　with　approximately　equiaxed　grains　of　only　4-6　&　mu;m.　Further,　the　ultimate　tensile　strength　(UTS)　and　yield　strength　(YS)　of　the　deposited　material　in　all　directions　differed　only　slightly,　with　the　strengths　in　the　longitudinal　direction　being　9.5　and　9.6%　higher　than　that　in　the　vertical　direction,　respectively.　Furthermore,　the　combined　UTS　and　elongation　of　the　FRAM-prepared　material　are,　to　the　best　of　the　authors＇　knowledge,　the　best　results　reported　for　printed　aluminum　alloys　using　ER2319　welding　wire.　The　interesting　research　results　presented　in　this　study　are　expected　to　have　significant　practical　application　implications　and　usher　in　further　research　in　this　field.
