When an inhomogeneous binary solid solution or alloy is annealed at constant temperature and constant pressure, it will become homogeneous. On the contrary, when a homogeneous binary alloy is annealed at atmospheric pressure but under a temperature gradient, i.e., one end of it is hotter than the other end, the opposite will happen and the alloy will become inhomogeneous.
