چکیده
Joining of dissimilar metals is required for numerous applications in industries such as chemical, energy and automotive. It challenging due to differences melting point, density, thermal expansion the being joined. Common welding techniques involve limiting solidification a narrow area leading high stresses potentially brittle intermetallic phases. Furthermore, geometric complexity these welded joints can be rather limited. Additive Manufacturing (AM) presents new joining metals. One emerging methods building functionally graded parts using Directed Energy Deposition (DED) spatially vary composition. In this paper, SS316L C300 maraging steel couple were joined by DED heat treated. 13 discrete composition layers selected metallurgical considerations, order ensure smooth transition properties microstructure. The mechanical as-built found similar SS part no phases interface.

متن کاملComparison of Maraging Steel Micro- and Nanostructure Produced Conventionally and by Laser Additive Manufacturing
Maraging steels are used to produce tools by Additive Manufacturing (AM) methods such as Laser Metal Deposition (LMD) and Selective Laser Melting (SLM). Although it is well established that dense parts can be produced by AM, the influence of the AM process on the microstructure-in particular the content of retained and reversed austenite as well as the nanostructure, especially the precipitate ...

Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...
