A possible solution to overcome these challenges are rapid alloy development (RAD) approaches. Integrated Computational Materials Engineering (ICME) employs thermodynamical simulations of expected phases and solidification simulations to gain further insight into the
microstructure and resulting properties. Promising alloys are then further tested experimentally in the AM process, usually in a first step by dry mixing of multiple elemental or pre-alloyed powders. For high throughput testing, the Extreme High Laser Application (EHLA) is used.
A new machine allows to transfer this technology to real 3D applications, which makes it feasible for high throughput sample production. Samples from elemental powders without pre-blending can be produced with different chemical compositions on one build plate. These
samples will be further analysed before the third step of this approach is initiated. It consists of a deep analysis of the most promising compositions using custom pre-alloyed powders.
