Abstract
Experiments have been conducted to examine the effects of binder composition on the mechanical properties of injection-molded, carbonyl iron sintered products. A solvent extraction debinding technique was used to quickly remove the binder and carefully control the carbon content. A high content of high molecular weight backbone binder component gives rise to a higher flow viscosity, but does not significantly enhance the green strength. The addition of a small amount of stearic acid can improve moldability by reducing the flow viscosity. A variance in sintered properties is related to the difference in carbon content and final grain size.
