You know, I’ve never figured out how some people (namely you) are
able to get Ti red hot and work it without it getting brittle.
If I so much as look at a torch in the presence of Ti, it shatters
“By the book” you shouldn’t anneal (or hot work) Ti in open
atmosphere, because it reacts with all the O2 and N2 to form brittle
oxides and nitrides that get sucked into the core of the metal,
making it brittle. (at least for me) I’ve had 1/4" (6mm) sections
snap like toothpicks just because they were torch annealed
(quickly). Total time hot? Less than 30 seconds, and the
embrittlement shot straight through the piece. (I’ve done it a bunch
of other ways too. Brittle every time.)
Meanwhile, here’s Hans torching a relatively thin section, bashing
on it hot, and not having any trouble with it at all.
And you guys wonder how medieval metalsmiths got seriously
Grumble, grumble, grumble…
