| Crystalline phases and mechanical properties of sintered hydroxyapatite/Ti (HAp/Ti), processed either by mechanical milling or mechanical alloying, have been investigated. Crystalline phases of sintered HAp/Ti were changed with Ti vol%, powder processing method and sintering temperature. When sintered at 1100℃ or 1300℃, formation of calcium titanate compounds were facilitated with HAp/Ti powders fabricated by mechanical alloying, compared to powders processed by mechanical milling. HAp/Ti with 20 vol% Ti, fabricated by mechanical alloying and sintered at 1300℃ for 4 hours in vacuum, showed flexural strength of 52 MPa and K_(10) value of 1.5 MP_(a m)^½, compared to 33MPa and 0.84 Mp_(a m)^½ of the pure HAp sintered sample. |
