The sintering of materials involves at least two processes: densification of the body and growth of grains in the body. The longevity of grains is usually achieved through the movement of grain boundaries. According to the classical theory of grain growth kinetics, the difference in free energy between the two sides of a curved grain boundary is the driving force that causes the interface to move ...
