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

采用金属注射成型技术开发了更复杂、更大尺寸的钛合金部件。获得的样品尺寸比传统的MIM组件大几倍。通过优化脱脂和烧结条件，使尺寸精度达到航空航天零件ISO标准。为了减少脱粘过程中的变形，在粘结剂组分中加入了聚酰亚胺粉末。最后，通过现场观察，证实了热脱脂过程中变形的减小。

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.
