Abstract

Duplex stainless steels (DSS) combine excellent corrosion resistance with outstanding mechanical properties. Typical applications can be found in chemical, gas and offshore industries, where corresponding components usually feature a high degree of customization. This makes additive manufacturing an economically interesting production approach. However, a major challenge in additive manufacturing of DSS is a precise process control to achieve the required material properties. In this work, DED-LB\M was used to process DSS 2205. A multistage experimental procedure was developed to generate nearly fully dense cuboidal specimens (relative density > 99.9 %). In addition, the complex interaction mechanisms between process parameters and resulting material properties such as microstructure and hardness were investigated. For specific process conditions, the desired ferrite-austenite balance of DSS could be obtained. Furthermore, the hardness was found to decrease with increasing build height and correlates with gran size as well as the slightly decreasing ferrite content.
