Boiling points of metals!
I have two questions:
1. Do metal alloys demonstrate boiling point elevation the way solvents with a solute in them do? And if so, would it be calculated in a similar
manner?
2. How does pressure affect the boiling point of a metal? I see boiling points listed for metals, but they never state at what pressure they were
taken.
Any information anybody has regarding boiling points of metals would be greatly appreciated. Also, if anybody knows of any books or other literature
on this topic, please speak up! I would love to buy a book on this topic.

Search for CRC Handbook of Chemistry and Physics...it contains much tables that can full your answers.
Hope to have helped

Also, does anybody know where I can find pressure/temperature/density relationships for silver vapor? I'll check the CRC, but won't be surprised if I
don't find it there.

Probably does. Zinc boils at 1600°F or so but I've poured non-boiling brass at 2200°F.
(No, I won't covert those. My "foundry" works in Fahrenheit and I like it that way!  )

"How does pressure affect the boiling point of a metal? I see boiling points listed for metals, but they never state at what pressure they were
taken."
Much the same way as it affects the boiling point of other things- higher temperature at higher pressure- roughly logarithmicaly.
As with most things, if the pressure isn't stated for a boiling point it's assumed to be 1 atmosphere.
In general there's nothing magical about metals so they should behave much the same way as other things e.g. with a bit of luck Raoult's law will give
the vapour pressure.
