Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:
