The preparation of pure-Ti compacts by metal injection molding (MIM) process was described in this paper. To reduce contamination at sintering process, the sintering was performed at low temperature range from 1198K to 1348K. On this sintering condition, the properties of sintered compacts were investigated.
When HDH powder (average particle size is 23μm) was used as the material, the compacts sintered at more than 1298K had high tensile strength (630MPa<) in spite of low density (92.5-94.5%). When gas-atomized powder (average particle size is 15μm) was used, the sintered compact had high density (-95%) and high elongation (15-20%) at low sintering temperature range (1248K-1298K).
