Combinatorial alloy development by LMD

The term Combinatorial Alloy Development is used for an approach to create material libraries, e.g. by the fabrication and testing of compositionally graded materials. At the chair for Materials Science and Technology of Metals, we employ an InssTek laser deposition unit equipped with four powder hoppers in a glove box with inert gas atmosphere to produce these concentration gradients. Through local testing and characterization, interesting alloy compositions can be identified rapidly and effectively in a high throughput approach. Additionally using the same machine, multi-material or compositionally graded components can be manufactured, which could not be produced through traditional metallurgy.
