Structure of alloys? (1 Viewer)

[dongwayne]

I have a test coming up and we have to research alloys. I know alloys are a mixture of metals and other elements.. but I need to relate the structure of alloys to that of a metallic bond.. preferably with a diagram. What does the structure of an alloy look like?

Here's an example.

Id assume that it is still the same type of metallic bonding, i.e. sea of electrons. Except that there would be different sizes of cations, giving the alloy special quatlies.

Btw, which module are you guys up to, or which have you done if not done in order?

We're almost finished water..
imo this topic was extremely boring -_-

I liked water lol ...i foud Chemical Earth boring :mad1:, it was like revision of year ten chem + a bunch of new stuff

Yeah.. it's not too bad actually.

Well, i am actually finding a lot of the course just a revision of what we have learnt already...and i am finding it very annoying:mad1:...but chemistry is still good

alloys..
here's a picture

basically the the metallic bond is what keeps the atoms together in an alloy...the delocalized electrons are attracted by the positive nuclei through out the metal's lattice which keeps them together
however, these bonds are not strong and therefore, don't effect the chemical composition but affect only the physical arrangement in the lattice..

hope that helps!:wave:
