Abstract
The present invention relates to a process for producing a component composed of titanium or titanium alloy by means of MIM technology. In this process, a homogeneous mixture of boron powder having a particle size of less than 10 μm, preferably less than 5 μm, more preferably less than 2 μm, and titanium powder and/or titanium alloy powder is produced, and binder is mixed with the homogeneous mixture of boron and titanium powder and/or titanium alloy powder and also, if appropriate, an additive in a kneader, the mixture is moulded by injection moulding to produce a green part, the moulded composition is subjected to chemical and/or thermal removal of binder to produce a brown part and the composition from which the binder has been removed is sintered at a temperature in the range from 1000° C. to 1600° C.
