Tools, Space and Aircraft, Automotive, Medical, Defense and others

Oral Presentation

Additive manufacturing (AM) has emerged as a powerful processing route for a wide range of materials. However, for refractory metals (RM), especially for Mo, W and their alloys, its implementation remains particularly challenging because of their unique combination of properties. Very high melting points, low-temperature brittleness, strong sensitivity to impurities, and high thermal...

14. Additive Manufacturing of Molybdenum: Defect Mechanisms and Alloying Strategy for Fully Dense and Crack-free Molybdenum Parts by PBF-LB/M

Dr Jakob Braun (Universität Innsbruck)

10/11/2026, 14:00

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

Molybdenum is a difficult-to-weld metal that, when processed by Powder Bed Fusion – Laser Beam (PBF-LB/M) is prone to cracking and residual porosity. This presentation addresses the crucial role of oxygen impurities driving the formation of such defects and the beneficial effects that can be exploited by utilizing carbon as an alloying element.
The effects of these two elements on...

13. MoC0.4 – From Lab to Industry in PBF-LB of C-alloyed Molybdenum

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

By processing carbon-alloyed molybdenum (MoC0.4) using Powder Bed Fusion – Laser Beam (PBF-LB) a unique fine-grained microstructure is achieved. This microstructure is characterized by molybdenum grains containing a subgrain structure of molybdenum cells embedded in a nanometer-sized Mo2C matrix. This material yields promising mechanical and physical properties, comparable to those of...

11. Additive Manufacturing of Tungsten: Challenges and Solutions in Laser PBF

Prof. Lukas Kaserer (Universität Innsbruck)

10/11/2026, 14:40

Laser Melting, Electron Beam Melting & Direct Energy Deposition Processes

Oral Presentation

Enabling additive manufacturing of tungsten (W) for components with properties that match or surpass those of conventionally manufactured powder metallurgical (PM) W parts is currently one of the greatest challenges in alloy and process development for PBF LB/M. For W, rapid solidification under steep thermal gradients typically produces coarse, columnar grains and high residual stresses,...
