Application of Cryogenic Principles to Emergency Metal Cutting - Creativity Award

这项研究的目标是开发一种紧凑型低温切割系统原型，该系统采用水射流切割原理用于紧急救援任务。设想的原型将使用低温流体，其应用温度足够低，可以通过局部积累的热应力和机械应力使结构材料脆化和断裂。低温流体产生的脆化将通过水射流技术来优化选定区域的金属切割工艺。这项研究的意义在于开发新一代紧凑型紧急刀具，使用低温流体取代火焰，最大限度地减少(或消除)火花产生的影响。

The objective of this research is the development of a prototype compact cryogenic cutting system that employs water jet cutting principles for emergency rescue missions. The envisioned prototype will use cryogenic fluid with application temperatures low enough to embrittle and fracture structural materials through a local build-up of thermal and mechanical stresses. The embrittlement resulting from the cryogenic fluid will be utilized through water jet technology to optimize metal cutting process in selective areas. The significance of this research is the development of a new generation of compact emergency cutting tools that use cryogenic fluid to replace flame and minimize (or eliminate) spark-generating impact.
