Generation of spherical microscopic samples with single droplet solidification (U01)

• Subject Area: Mechanical Process Engineering
• Term: from 2016 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 276397488

Single droplet processes with metallic melts offer the possibility to generate spherical micro samples for high throughput. The solidification takes place conventionally during free fall in a stagnant gas atmosphere. Within this project, new cooling conditions will be developed using a concurrent flow with variable gas atmospheres and conductive heat transfer after droplet impact. drop oscillations after droplet formation will be evaluated to determine the surface tension in-situ.
