On the theory of normal and abnormal grain growth

A growth equation for individual grains in single-phase materials is suggested. It is used to calculate a rate equation for normal grain growth and the size distribution in the material. It predicts a maximum size of twice the average size. The theory is modified to take into account the effect of second-phase particles. null In an alternative treatment the array of grains is described in terms of a kind of defects introduced into a perfect...
