Buh?? What in God's name were
those?? Not a single one of those talk about thermite
at all. They do nothing but reference iron sulfides, and one of them discusses a unique ionic species of it. All 3 are talking about what happens to iron-sulfide
in planetary cores. What the

does any of
that have to do with sulfidation corrosion?? Not a single one of them implies that such high pressures are
necessary for the formation of iron sulfides; on the contrary, the implication in each is "what's the difference between what we're studying
and normal conditions outside planetary cores.
Plus, iron sulfide species just sitting in the ground is not the same thing as carbon steel getting corroded. That's an incredibly stupid association to make. Just plain
stupid.
That response is as useless as it gets. It doesn't answer the challenge in any aspect. Not the least of which is that none of the linked papers talk about thermite
whatsoever.
Jesus. "Reach" doesn't even begin to describe that.
