Challenge to More Complicated and Large Sized Components Using Next Generation Ti Alloys Trough MIM process.

More complicated and large sized Titanium alloy components were developed through metal injection molding process. The size of obtained specimen was several times larger than conventional MIM components. The dimensional accuracy was similar to ISO standard for aerospace components by optimizing the debinding and sintering conditions. In order to decrease the deformation during debinding process, polyimide powder was added to the binder component. Eventually, it was confirmed that the deformation was decreased during thermal debinding through in situ observation.
