Alloy development for additiv manufacturing

The introduction new processes offer great potential for specific alloy developments due to new process conditions. We investigate the influence of selective electron beam melting on technical alloys based on Iron Aluminides, Nickel, Copper as well as on amorphous metals and shape memory alloys.
For Iron aluminides, the focus is on the influence of additional elements such as Boron and Titanium on the workability, the microstructure and the resulting properties. 
Concerning pure Copper and Copper alloys our focus is on the influence of minor elements or contaminations such as Oxygen or Phosphorus on the resulting properties, in particular the achievable heat conductivity.
