분말사출성형을 통해 제조된 소결체의 기공율에 따른 강도예측모델
A Model for the Relation between Strength and Porosity in Sintered Parts Produced by Powder Injection Molding Process
초록
In the present study, a new approach to predict the strength of sintered materials has been carried out and a new framework combining neck growth model and ideal pore model has been established based on the results of tensile tests on powder injection molded specimens with the various porosity. Powder injection molding (PIM) uses the shaping advantage of injection molding but is applicable to metals and ceramics. PIM delivers structural materials in a shaping technology previously restricted to polymers. 17-4 PH stainless steel powders with average diameters of 10
