Abstract Scope |
The additive manufacturing of tool steels have been limited to either low carbon maraging steels, or extreme pre-heating temperatures for materials such as H13 or D2, to avoid crack formation. This study investigates the use of austenite stabilizing elements, to avoid the phase transformations that have so far been limiting the processability of tool steels. The study will show L-PBF of a broad range of chemical compositions, identifying an area with high processability without pre-heating, due to austenitic solidification. A selected composition is chosen for further investigations, show-casing that a hardness of 60 HRC can be achieved after heat treatment. |
