Well, SpaceX uses inconel. They also must have a quite good understanding of pyrotechnics, as they need to use that in a lot of places, eg. stage separation.
So I'd say yes, at least on the tech transfer part.
I don't think so. At least, it hasn't been publicly reported as far as I know. So although I'm not saying it's impossible, I'd be very interested to know the source for your statement?
