There is no reason why a titanium miniature that small would raise any eyebrows. Titanium & titanium alloy are used to manufacture golf clubs, eyeglass frames, water bottles, etc., and it is hard to imagine that titanium alone would cause any suspicion.

If it small enough and if it looks harmless enough you should be fine putting it in your carry-on luggage. However, if you want to be sure that it will not be taken away by airport security you should follow the golden rule and put in in hold luggage.

You should check with the security. I had to throw my guitar key when is used to tighten the guitar neck in trash. When they found in scanning machine that there was some metal inside my bag. so double check before flying there can be some restrictions to metal objects.
