Additive manufacturing of a carbon-martensitic hot-work tool steel using a powder mixture - Microstructure, post-processing, mechanical properties

F. Grosswendt et al.

Summary: This study investigates the processing of hot-work tool steel using laser-based powder bed fusion of metals, applying a chemically homogeneous and dense layer of powder mixture prior to densification. Evaluation of suitable process parameters and post-treatments led to achieving full redensification and chemical homogenization of the processed powder mixture, resulting in improved hardness compared to the cast reference.

Laser Powder Bed Fusion (PBF-LB/M) Process Strategies for In-Situ Alloy Formation with High-Melting Elements

Florian Huber et al.

Summary: In this study, the effects of PBF-LB/M process parameters and exposure strategies on the fusion of high-melting elements in a Ti-matrix were investigated. It was found that adjusting the process strategies is crucial for achieving complete dissolution of high-melting alloying elements, with a significant decrease in unmolten particles and successful fusion observed for certain parameter combinations.

Influence of solidification structure on austenite to martensite transformation in additively manufactured hot-work tool steels

Chia-Ying Chou et al.

Summary: This study investigates the microstructure of a hot-work tool steel manufactured using laser powder-bed fusion (L-PBF) and its response to post heat treatment through microstructure characterization and computational thermodynamics and kinetics. The high solidification and cooling rates during L-PBF process lead to the formation of an austenite phase with segregated alloying elements and solidification carbides. The austenite is partly transformed into martensite at lower temperatures, and micro-segregation can be predicted and compared with measured profiles at a nanometer scale.
