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

金属熔体的单液滴工艺提供了高通量生成球形微样品的可能性。凝固通常发生在停滞的气体大气中自由落体的过程中。在这个项目中，将开发新的冷却条件，使用可变气体气氛的并发流动和液滴撞击后的传导传热。将评估液滴形成后的液滴振荡，以确定现场的表面张力。

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.
