Abstract Scope |
Through a Small Business Innovation Research (SBIR) contract, Quadrus Advanced Manufacturing (QAM) investigated the effect of mechanically alloying 4wt% TiC nanoparticles into 316L stainless steel powder on the alloy’s as-built microstructure when processed via laser powder bed fusion (L-PBF). QAM used a planetary ball mill to coat the outside of the 316L powder with the TiC nanoparticles. The as-built microstructures of both the non-reinforced and reinforce 316L were compared. Additionally, QAM performed preliminary uniaxial tension testing and Rockwell hardness testing to examine the difference in each alloy’s mechanical properties. Lastly, representative samples from both alloys underwent EBSD analysis to better understand the differences in the grain structure and orientation responses seen in each alloy. |
