In-situ observation during debinding and sintering was performed to clarify the debinding mechanism. Polyimide powder was added as the binder component to keep the shape for the debinded compact. Polyimide powder was confirmed to be remained after debinding. Carbon content of polyimide specimen was increased, thus tensile strength of stainless specimen was increased by carbon solute effect. Moreover, silicone robber was added to the binder. Sintered density and tensile elongation was improved.

对脱脂和烧结过程进行了原位观察，以阐明脱脂机理。加入聚酰亚胺粉末作为粘合剂组分以保持脱粘压坯的形状。确认脱脂后残留聚酰亚胺粉末。聚酰亚胺试样中的碳含量增加，从而通过碳溶质效应提高了不锈钢试样的拉伸强度。此外，在粘合剂中加入了有机硅橡胶。烧结密度和拉伸伸长率得到提高。
