This study compared the properties of AM-produced 304 stainless steel via the direct energy deposition (DED) AM process with wrought 304 stainless steel. The samples were studied in their as-built or as-received condition; and the characterisation analysis included micro-structural evaluation, hardness tests, Charpy impact testing, tensile testing, and X-ray diffraction. The results demonstrated that, in general, the strength characteristics of the AM sample exceeded those of the wrought material other than for toughness.FulltextenAdditive manufactureMechanical testsMicro-structureStainless steelXRD analysisInvestigation of the properties of direct energy deposition additive manufactured 304 stainless steelArticleHoosain, S., Tshabalala, L.
