Microstructure of MS1 maraging steel in 3D-printed products afres semi-solid processing

Original language description

The importance of 3D printing in today's industry is continuously increasing. One of the materials which are frequently used in this process is the precipitation-hardenable MS1 Maraging steel whose properties after conventional treatment have been thoroughly mapped. Maraging steels belong to the strongest homogeneous steel materials ever. Their alloying additions include cobalt, molybdenum, titanium and aluminium, and their unusual properties make them candidates for heavy-duty parts operating predominantly under dynamic loading. Semi-solid processing of this particular steel enables near-net shape products to be made using a single production step. Furthermore, unconventional microstructure and physical, chemical and mechanical properties can be obtained by this process. The semi-solid processing route and the mechanical properties achieved by it can expand the potential uses of this material. Semi-solid processing of small volumes of material has already been mastered with high-alloy steels which offer a wide range of forming temperatures. However, as this process is technically demanding, its use for medium and low-alloy ultra-high-strength steels has not been explored in greater detail yet. In the present experiment, MS1 Maraging steel was studied. The experimental feedstock was made by 3D printing. The initial set of semi-solid processing parameters was proposed on the basis of calculation and then tested experimentally. In this article, description of the microstructures of this steel before and after several semi-solid processing routes is given, based on examinations using optical and electron microscopy.
