Boundaries<br />
Temperature dependence<br />
• The growth of new grains requires motion of grain<br />
boundaries. Boundary migration occurs by the<br />
transfer of atoms across the boundary which is a<br />
diffusion-like process.<br />
• Solutes have a strong effect on boundaries because<br />
the interaction leads to segregation (generally an<br />
excess of solute on the boundary). In effect, moving<br />
the boundary forces the solute to move with it.<br />
• A suitable measure of the “reaction rate” is the time<br />
for 50% recrystallization.<br />
