Fundamental understanding of a new and innovative process combining sheet metal forming with additive manufacturing is the main goal of this research work. Schweissen und Schneiden , p. Evaporation leads to material loss, has influence on the melt pool dynamics and changes the alloy composition. Procedia Computer Science 18 , p. September Open Access:

Contact Imprint Sitemap Deutsch. We use combinatorial methods for the development of new alloys that allow the creation of large material libraries based on thermodynamic predictions. Selective electron beam melting of a copper-chrome powder additivr In: Target oriented material development has to be based on a profound understanding of process-inherent mechanisms.

The thesis starts by introducing the main aspects of the technology, to fertiyung a common understanding, which is key for understanding the dissertation. The main challenge of this project is to develop innovative processing strategies based on a sound theoretical process understanding in order to produce crack-free and preferably single crystalline samples, also with higher geometric complexity.

Insights gained hereby are also utilized to analyze two representatives of the branch of industry by way of example. Powder layer deposition algorithm for additive manufacturing simulations In: Commercial available EBSM machines show strong limitations with respect to the beam power, beam quality and beam control.

Simulation on the scale of the powder particles reveals phenomena which result from the complex interplay between beam, powder and melt pool.

Presently science and research focuses primarily on questions regarding materials and processes, while ignoring or missing out the discussion about economic and social fertigunv.

A conclusion that can be drawn is that the room to maneuver is extended with regard to complexity, efficiency enhancement, and variety of versions. In order to demonstrate the potential of structural catalysts we consider the methanol synthesis.
