抄録

Tensile properties of sintered Ti compacts prepared by metal injection molding process were investigated. Powder materials used for this study were pure Ti powders, whose average particle sizes were 13μm and 23μm. After debinding, the green compacts were sintered at various temperatures for 7.2ks in vacuum (10^-3Pa order). Then the green compacts were placed in a case with Al₂O₃ powders or BN powders to compare the oxygen contents in the sintered Ti.<BR>13μm powders enabled to sinter at lower temperature than 23μm powders, so the Ti compact sintered at 1298K had 0.2% offset yield stress of 485 MPa, modulus of elasticity of 101 GPa and tensile elongation of 18%. The tensile elongation was influenced by the oxygen content in sintered Ti. The oxygen content increased with sintering temperature when the green compacts were sintered in a case with Al₂O₃ powders. But, when BN powders were used instead of the Al₂O₃ powders, the oxygen content changed hardly by sintering temperature. Consequently the tensile elongation was improved drastically.
