초록
The present investigation has been performed on full densification behavior and mechanical property of the powder injection molded Fe-8wt%Ni nanoalloy powder. The net shaping process of the nanopowder was conducted by powder injection molding (PIM) process. The key-process for fabricating fully densified net-shaped nanopowder by pressureless sintering is an optimal control of agglomerate size of nanopowder. Enhanced mechanical property of PIMed Fe-Ni nanopowder is explained by grain refinement and microstructural uniformity.
