I am looking for on a silver-titanium alloy.
I can't help you with that, but thought it might be worth mentioning
that I met a local materials engineer at a party a few years ago who
had grown gianr single crystals of a titanium/gold alloy. He was
very disappointed that the process was not picked up for some
industrial application, and clearly considered it basically a
scientific oddity. He did say he made a pair of earrings for his
wife out of it.
I don't recall his name, though I could get it if somebody wants to
buy his process...
