A common question about laser eye surgery is simply, âHow much is LASIK?â The best answer is this: There is no single answer. The cost of LASIK varies widely from the incredible $299 per eye on TV commercials to the equally incredible $5,000 per eye.
A alloy is a mixture or solid solution of two metals or a metal and a non metal. Mixtures of metals, any metals typically when one or more are molten.
The dependence of viscosity on the composition of liquid solutions is illustrated by Fig. 3.9 for molten zinc-aluminum solutions (7); and by Fig. 3.10 for iron-carbon alloys (8). It can be seen that the behavior of molten alloys cannot be described by simple addition rules.
