Symposium Additive Manufacturing: Processing Effects on Microstructure and Material Performance
Presentation Title The Effects of Alloy Composition on Microstructure and Mechanical Properties of Duplex Stainless Steel Produced by Additive Manufacturing
Author(s) Andrew D. Iams, Todd A. Palmer
On-Site Speaker (Planned) Andrew D. Iams
Abstract Scope While additive manufacturing shows great promise for production of complex part geometries and for repair applications of many alloy systems, the additive manufacturing of duplex stainless steel alloys have been limited by the inability to maintain a balanced ferrite/austenite microstructure in the as-deposited condition. In order to investigate the impact of the complex thermal histories inherent to the additive manufacturing process on the microstructure and mechanical properties, a laser-based directed energy deposition process was used to fabricate lean (UNS S32101), standard (UNS S32205), and super (UNS S32507) duplex structures. The effects of post-process hot isostatic pressing on duplex stainless steel microstructures and properties are also investigated.
