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

采用金属注射成形工艺，可以开发出更复杂、更大型的钛合金构件。所获得的试件尺寸是传统MIM构件的数倍。通过优化脱脂和烧结工艺条件，获得了尺寸精度接近ISO标准的航空零件。为了减少脱脂过程中的变形，在粘结剂组分中加入聚酰亚胺粉末。最后，通过原位观察证实了热脱脂过程中变形减小。

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.
