Has anyone ever tried alloying iron with gold into some sort of "goldsteel"?

If memory serves, gold and iron are two metals that can't form an alloy.
[up]Yup: you'd have to mix an unholy cocktail of metals just to get iron interested in vaguely going near gold. By which point, you're not talking a lot of gold — but are talking a lump of something you can't do much with. <_<

Alloys tend to work better if you're using metals that are at least close enough on the periodic table for government work.

Well, actually you're talking about solubility where the electro negativity is one factor. The way the atoms are packed and atomic size are also factors (thus steel: carbon atoms are so small that they go in between the iron atoms).

Though solubility is not the whole story: some very insoluble solutes (alloys are solid solutions: think salt in water but instead think ice) can have a large impact on the properties even in minute amounts: tin and silver in aluminum alloys for example.
@Marq: Is this close enough? Not actually an alloy with steel, but basically the same idea.

not sure if this thing's even still active, but anyone good with classifying electrolytes? I'm supposed to classify several and I don't quite get what your supposed to do to sort between strong/weak/non-electrolytes.
The system doesn't know you right now, so no post button for you.
You need to Get Known to get one of those.
