Abstract:
Laser Powder Bed Fusion (LPBF) has become an attractive alternative to conventional processing routes over the past years. While some alloys are already processed in series production, the overall amount of available materials is low. Due to the high price of specially atomized powders, material variation is often neglected. This work covers the blending, in-situ processing and testing of metal powder blends and the produced specimen. Different metal powders are blended to create a Super Duplex Steel. The powder blend quality is assessed by different methods. Heat treatments , corrosion tests and EDX analyses determine the specimen quality as well as tensile tests. The properties of the created alloy is compared to conventionally produced duplex and super duplex steels in order to show the potentials of this approach.
