Jerry, I need to do a bit of research to see where the boundarys are. I may try to patent the process if I think it's patentable. I've tried it on tungsten and aluminum without success. That makes sense from the hardening aspect, which I had to verify. I haven't tried stainless yet, which I think should work. I'll need to keep the process secret at least for a while. It looks like it should have pretty good potential.
Titanium can indeed be pretty scary if it lights. It's like magnesium in the way it burns. I would say to try that only in a full argon shield if you try that again. Titanium readily absorbs oxygen at higher temperatures. Once the oxides form, nothing sticks together. I've seen titanium mokume made by a hydraulic press with an argon shield and kiln attached in a book by Ian Ferguson called Mokume Gane. By using heat and extreme pressure, they are able to get metals that don't usually go together like copper and monel, mixed aluminum alloys, iron and stainless steel, copper and titanium, and copper and iron being fused together. Stainless or titanium damascus is pretty similar in concept. If you are trying stuff like that, you should get the book.
