Magnesium lead phase diagram

Hi all, I saw a [post earlier today](https://www.reddit.com/r/ufo/comments/e6td91/chris_cogswell_discusses_the_metamaterials_and/) about Chris Cogswell discussion regarding TTSA's "metamaterials" (massive emphasis on the quotation marks) and how to prove whether they're made by humans or not. Reading some of his comments, I realize he is missing information that I have access to and it's not fair to him or anyone else in the community. I was reached out to by an American scientist who owns a ve...

My materials science textbook (Callister 7e) states that almost all metals harden by alloying. I haven't been able to find any source that states which metals don't harden with alloying. Can anyone shed light on this for me? Also, if there is a metal that does not harden by alloying, can you explain the mechanism for why it is harder pure?
