摘要：

205A　aluminum　thin　wall　part　was　additively　manufactured　using　cold　metal　transfer　(CMT)　equipment.　The　influence　of　alpha-Al　grains,　Al2Cu　phase,　and　pore　characteristics　on　the　in-situ　tensile　behavior　was　investigated.　The　experimental　results　show　an　enhancement　in　the　ultimate　tensile　strength　(UTS)　in　the　as-deposited　sample,　as　compared　to　its　as-cast　counterpart.　This　can　be　largely　attributed　to　the　presence　of　the　refined　alpha-Al　grains　more　than　dot-like　Al2Cu　phase.　A　slightly　deteriorated　plasticity　was　observed,　which　was　mainly　related　to　micro-scaled　spherical　pores　with　a　relatively　high　porosity　of　3.51%.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
