Additive Manufacturing of Metals and Alloys


Lecturer(s) :

Leinenbach Christian
Logé Roland




Every 2 years


This course is designed to cover a number of materials science aspects related to the field of additive manufacturing of metals and alloys, and to provide an in-depth review of corresponding fundamentals.


1. Introduction to Additive Manufacturing (AM) of metals and AM methods (LPBF, EBM, DED, other methods such as binder jetting)


2. Powder fabrication and characterization


3. Interaction between beam (laser, e-beam) and material, heat formation and heat flow in the material


4. Fundamentals of rapid solidification of metals and alloys


5. Microstructure formation and control during AM


6. Residual stresses and warpage, defects (porosity, cracks) in AM parts


7. Post-treatments and associated microstructure evolutions


8. Mechanical properties of AM parts (static, cyclic), mechanical anisotropy


9. Material specific considerations: AM of steels, Ni alloys, Ti alloys, Al alloys; AM of precious metals and Cu alloys; AM of special materials (MMCs, gradient materials/multimaterials); Development/optimization of alloys


metals and alloys, laser processing, electron beam melting, solidification, microstructure, post-treatment, mechanical properties, residual stresses
