Metal injection molding (MIM) process allows nearly full dense and net shaping of a variety of engineering materials. Especially, the application of MIM process to hard and brittle materials such as Fe-Si-Al (Sendust) alloy demonstrates the potential of this novel process.
This study considers the processing of Sendust alloy compacts through the MIM techniques using different types of powders, gas and water atomized powders. Soft magnetic properties were strongly influenced by the grain size and retained oxides. By the continuous process combining the debinding and sintering steps together, high performance soft magnetic properties due to the reduction of oxides and coarse grain size were obtained by using gas atomized powder.
