I guess it's time to confess. Even though I did take some metallurgy in college, and worked in two labs where materials were tested, I don't have a clue what I was asking in my made up question! I have a lot of books on tech. stuff, and I looked in the glossary and found a treasure of terms to use. So don't feel bad for not being able to answer my "question". Wouldn't it be ironic if the real Fermilab was working with the three metals I mentioned and sent men in black over to find out how I knew about their project!
