Forming alloys?

Question

Ive read, and been told that some alloys are formed simply by melting the two metals and then mixing them together.

But alloys are homogenous (uniform) mixtures

If this really works, how come the metals mix evenly ? why dont they mix randomly so that the alloy is not uniform?

If this doesnt work, how are alloys formed? or are there any other ways to form alloys ?

Oh and if the reason that mixing them makes it uniform if that the metal dissolves in the other metal, then how does the dissolving work? like for salt and water, the salt splits into its ions, what happens to the metals?

Answer 1

It is true that alloys are formed by melting two or more metals together. It is not true that they are all homogenous. Actually, very few are homogenous. Alloys are selected to provide particular characteristics, for example, yield strength, electrical conductivity, impact strength, corrosion resistance, and others. Alloys can achieve different characteristics because the inhomogenieties can be controlled thru metallurgy. Some liquid metals actually form immiscible mixtures, like oil and water.
