SYNOPSISPure Ti, which is used in the field of Metal Injection Molding (MIM), can be used to produce parts with complicated shapes. But, since oxidation, nitrogen and carbonization are generated during the debinding-sintering process, the mechanical properties of the sintered material cannot achieve the same level as those of the ingot material. Accordingly, we have studied the debinding and sintering methods by using various binder systems. This paper reports on the mechanical properties required by customers (0.2%proof stress of 216 MPa or more, tensile strength of 343 to 510 MPa, and elongation of 10% or more)and the development of the parts production process.
