| Abstract Scope |
This study aims to investigate the effects of recycling on the properties of Ti-6Al-4V powder exposed to laser engineered net shaping (LENS) processes. PREP and Plasma-atomized powders from a single feedstock with different size distributions (i.e. small for 45-90 µm sifted powder, large for 90-150 µm sifted powder, and unsifted for the as received powder) and levels of usage (i.e. virgin for powder processed 0-1 times, used for 2-5 times, and used+ for 6-9 times) are considered in this study. A combination of LENS process parameters is employed using the Taguchi design method to narrow down significant parameters related to part performance. This study will report on powder analysis including chemical composition, oxygen analysis, morphology, size distribution, flowability, phase, and grain structure of samples. Understanding the role of powder morphology, porosity, phase, and oxygen content is required to develop robust processing parameters for additive manufacturing and reduce cost of production. |
