An Investigation on a New Type of Fe-Ni Alloy in MIM Process

Abstract:

Article Preview

Small particle size powder of Fe and Ni was used as raw materials (the particle diameter of metal injection molding (MIM) was 0.5-20μm generally) [1], and the wax-based polymer was used as binder, a new type of Fe-Ni alloy for semiconductor was prepared by the MIM. The processes which include injection debinding and sintering were studied as well as the properties. Metallographic analysis and XRD analysis showed that the alloy was a single stable organization of austenite (γ phase) whose expansion coefficient was low, and the microstructure was uniform and dense. The parts formed by MIM have high forming quality and forming precision as well as lower processing and manufacturing cost.So the MIM opened up a new way for processing small complex parts.
