“…[21,22] Therefore, the complete sintering of Fe-alloy powders could be achieved because of the containment of liquid phase even when sintered at 1200°C or 1250°C, lower than the sintering temperature of SS316L powders. Furthermore, the reduction of production costs due to the decreased sintering temperature and time could be achieved.…”

In this study, the powder injection molding (PIM) process was applied to Fe-alloy powders. Microstructure, hardness, wear resistance, and corrosion resistance of the PIM specimens were analyzed and compared with those of a conventional stainless steel, SS316L. When Fe-alloy powders were injection molded and then sintered at 1200°C or 1250°C, completely densified specimens with almost no pores were obtained. They contained 63 to 80 vol pct of hard (Cr,Fe) 2 B dispersed in the austenite or martensite matrix. Since these (Cr,Fe) 2 B borides were very hard, thermally stable, and corrosion resistant, hardness, high-temperature hardness, wear resistance, and corrosion resistance of the PIM specimens of Fe-alloy powders were 2 to 5 times as high as those of the stainless steel. Such property improvement suggested new applicability of the PIM products of Fe-alloy powders to structures and parts requiring excellent mechanical properties.

“…On the contrary, when STS 630 powders were sintered at 1350 1C, far lower than the melting temperature (1430 1C) [24], where liquid phase was not present, a considerable amount of pores (about 2 vol%) were generally contained in the sintered product [25,26]. Therefore, the complete or near-to-complete sintering of F1 alloy powders could be obtained because of the containment of liquid phase even when sintered at 1165 1C, lower than the sintering temperature of STS 630 powders.…”

“…In contrast to previous researches about backbone binders mainly focusing on rheological behavior [13,14], pore structure evolution [15], and debinding process [16,17], investigations on the molding behavior and sintered properties have been made in this study with aim to explore the suitable backbone binders for achieving the defect-free and excellent mechanical properties of parts in wax-based binder system via CIM.…”

Abstract:In this work, various backbone binders were used in wax-based binder system to formulate zirconia parts by ceramic injection molding (CIM). The effect of different backbone binders on the molding, debinding, and sintering behaviors was investigated. After blending process, the feedstock using multi-polymer components exhibited more homogeneous structure compared with that using the mono-polymer ones due to the synergistic effect of multi-polymers. During solvent debinding, some defects such as "slumping" and "peeling" appeared in the parts containing ethylene-vinyl acetate copolymer (EVA), but they were not found in the parts with other thermal polymers. Also, as for the parts after sintering, the one using low density polyethylene (LDPE) and high density polyethylene (HDPE) as backbone binders presented a more uniform microstructure with finer zirconia grains among all the investigated compositions, and thus obtained the highest flexural strength (~949 MPa) and relative density (~98.9%).
