Conventional　fabricating　methods　of　TA2–304　SS　laminated　metal　composite　(LMC)　(e.g.,　hot　rolling,　hot　stamping,　and　explosive　welding)　have　difficulty　in　removing　brittle　Ti–Fe　intermetallic　compounds　(IMCs)　and　are　not　suitable　for　the　preparation　of　the　small　size　structure　components　or　transition　joints.　Additive　manufacturing　of　LMCs　has　the　potential　to　achieve　the　desired　microstructure,　properties,　and　structure.　In　this　study,　TA2–304　SS　LMC,　which　has　been　extensively　employed　in　pipe　flanges　of　nuclear　plants　and　bows　of　sonar　dome,　was　well　fabricated　by　utilizing　directed　energy　deposition-arc　(DED-arc)　and　copper‑nickel　alloy　transition　interlayers,　and　the　formation　of　brittle　Ti–Fe　IMCs　was　suppressed.　The　results　of　this　study　indicated　that　the　standard　deviation　of　the　height　of　the　surface　morphology　reconstructed　by　adopting　Python　VTK　technique　was　evaluated　as　0.67.　Furthermore,　copper‑nickel　transition　interlayers　possessed　the　capability　of　isolating　Ti　from　Fe　atoms　through　the　formation　of　laminar-distributed　microstructure.　Specifically,　the　Interlayer1　was　comprised　of　(Fe,　Cr)　grains　with　different　shapes　and　small-size　(Cu)　equiaxial　grains,　Interlayer2　covered　large-size　(Cu,　Ni)　dendritic　grains　and　intergranular　(Cu),　and　the　TA2　layer　comprised　α-Ti　and　Ti2Cu.　The　result　also　showed　that　thermal　cycle-induced　recovery　and　recrystallization　and　diffusion-induced　elemental　interaction　accounted　for　the　different　microstructures.　Moreover,　the　interface　between　the　TA2　and　Interlayer2　layers　contained　TiCu4　+　(Cu),　Ti3Cu4　+　TiCu4,　Ti2Cu　+　TiCu,　and　TiCu　+　Ti2Cu　eutectoid　microstructures,　which　resulted　in　the　highest　hardness　of　450Hv　as　well　as　crack　initiation　and　extension.　Furthermore,　due　to　the　uniform-distribution　of　microstructure　in　the　absence　of　brittle　IMCs,　the　average　shear　strength　was　234.0　MPa,　which　reached　the　strength　of　the　conventional　method　and　conformed　to　the　standard　requirements.　Multiple　groups　of　galvanic　reactions　between　different　transition　materials　can　result　in　reduced　corrosion　resistance,　and　the　oxidation-reduction　reactions　can　lead　to　the　formation　of　massive　oxides.　©　2023
