Topic
- Controlling the solidification of bulk metallic glasses (BMG) is supported by fundamental thermophysical understanding combined with structural evaluation
- Challenges for structural research followed by implementation into the industrial workflow: multi-phase systems, metastable phases, phase separation, preferred orientation, nano-micro-crystals, crystallinity, strain & relaxation
