The　phase　constitution,　the　microstructural　growth　behavior,　and　the　anti-indentation　performance　of　2Cr13　thin-wall　part　were　successfully　tailored　through　inter-layer　dwelling　time　alteration　using　cold　metal　transfer　(CMT)　technology.　The　short　inter-layer　dwelling　time　induced　the　presence　of　a　low　amount　of　gamma-Fe　phase,　as　well　as　extremely　elongated　ferrite　grains　containing　ultrafine　needle-shaped　martensite　throughout　the　entire　part.　This　finally　led　to　a　narrow　fluctuation　in　microhardness.　The　long　dwelling　time　contributed　to　the　alpha-Fe　phase　formation　only　and　a　periodic　microhardness　trendline,　which　was　related　to　a　periodic　microstructure　featured　by　martensite　laths　within　the　block-shaped　ferrite　matrix.　This　method,　in　an　intentional　manner,　could　be　adopted　to　manufacture　a　particular　component　with　local　properties　that　are　altered　with　location　through　a　single　material　deposition.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
