Crystallized titanium

Yesterday I saw in a local group, the guys made jewelry and knife bolsters from this material. As far as I understand, an ordinary titanium alloy is heated almost to the melting point and then, with the help of a microcontroller, the temperature in the furnace slowly decreases over a day or more. Depending on the cooling rate and composition of the alloy, crystals are formed that become visible after polishing and pickling. If you make a lantern from such material, then it can always be polished and re-etched or anodized. Like voluminous Damascus, but not Damascus. By the way, it looks a bit like meteorites, since they also have a rather large crystalline structure.

Oh, I'd like to make a lantern out of something like that. But now I can't do it temporarily, but maybe someone didn't know about such material and wants to do it himself :cool:

From the point of view of a technologist, this is simply a deterioration of the material, it cannot be compared in strength and other parameters with the original alloy, but for a beautiful lantern, strength is more than enough. This opens up a few additional artistic possibilities, such as sandblasting some, polishing some and etching some and you get 3 different looks on 1 lantern. I saw something similar in Damascus knives

I might be wrong, but massive crystals are a breaking point in any metal. Of course, if parts will not get any mechanical stress it is not an issue.

In the early 2000s, Buck made a batch of knives out of this titanium. In my opinion, they chose an unsuccessful surface treatment - the crystals were not very pronounced and it looked like Zinc
