Abstract: Machined titanium chips are normally recycled as non-ferrous scrap metal, however, one approach is to recycle titanium chips to construct as lightweight sandwich panel with high energy absorption capabilities. Titanium can be a very valuable scrap valued metal along with other types of rare alloys. Five different types of Ti-6Al-4V machining chips were recycled in their solid state using equal channel angular pressing (ECAP). Titanium processing and recycling uses less energy than sourcing and producing components from raw materials, which saves money and creates less pollution. 또한 롯데케미칼 PET는 보다 낮은 온도에서 성형할 수 있어, Cycle time이 짧고 유틸리티 코스트를 절감할 수 있습니다.
