5 ) Fn = B ( Unti – Un ) – B ( un – Un - 1 ) , the first term in parentheses on the
right being the increase in length of the bond between atoms n and n + 1 , the
second term being the increase in length of the bond between atoms n and n – 1
.

A problem is posed by the presence of dislocations in cast and annealed crystals
. No dislocations can be present in thermal equilibrium , because their energy is
much too great in comparison with the increase in entropy that they produce .

If the alloy is held at a high temperature where some particles grow at the
expense of others , L increases and the strength drops . ... When a dislocation
moves , leaving its solute cloud behind , the energy of the crystal must increase .
