In article , Ken Vale says...

Can Iron Pyrite (fools Gold) be heat treated? What about Bravoite
(basicially Iron Pyrite with up to 20% Nickel)?

Heat treated in what fashion, the way the harder phase in
carbon/iron alloy is quench frozen in?

No, because Iron sulfide doesn't have the same phase diagram
features that the iron/carbon alloy does.
