Metal Injection Molding of Mechanically Alloyed Powders

Abstract

Advanced Materials can be fabricated by mechanical alloying. However, the small size of the mechanically alloyed powders makes them poorly suited for many consolidation methods. Metal Injection Molding (MIM) has the capability of making net-shape parts with a high final density. This paper describes research on the compatibility of mechanical alloying with MIM. Powders of 17-4PH stainless steel and NiTi intermetallic alloys have been produced by mechanical alloying. These powders have been injection molded, debound, and sintered. Results of feedstock characterization, injection molding parameters, sintering and final mechanical properties will be presented.
