Processing of Net-shaped Fe-Ni Nanomaterials by Powder Injection Molding

Abstract

This paper provides an overview on our recent investigations on the processing of net-shaped Fe-Ni nanoalloy powder and related material properties. The key-process for fabricating fully densified net-shaped nanopowder by pressureless sintering is an optimal control of agglomerate size of nanopowder. Especially, the pressureless sintering process is inevitable for consolidation of the Powder Injection Molded nanopowder. The mechanical- and corrosion properties of the PIMed Fe-Ni nanopowder are discussed in association with the microstructure of sintered nanoagglomerate powder.
