WEBINAR | Influence of In-Situ Heat Treatment on the Microstructure of Laser Powder Bed Fusion (LPBF) Processed PM23 

High-speed steel PM23 (1.3344) is widely used in cold-working applications due to its excellent combination of wear resistance, toughness, and machinability. Despite its attractive properties, Laser Powder Bed Fusion (LPBF) processing of PM23 remains challenging because rapid solidification and steep thermal gradients promote crack formation and porosity. 

In-situ heat treatment during  Laser Powder Bed Fusion (LPBF) has emerged as a promising strategy to reduce thermal stresses and improve part integrity. However, the effectiveness of this approach varies throughout the build volume, particularly as component height increases and thermal resistance changes. 

This webinar presents a detailed investigation into the resulting microstructures and the factors influencing their development. Particular attention will be given to the impact of in-situ heat treatment on crack susceptibility, porosity, and microstructural variations across different regions of the test specimen. 

Attendees will gain valuable insights into the complex interactions between LPBF process parameters, thermal history, and final material performance.
