b.
Figure 2 shows another ball-and-stick model of a very small crystal of a-
Polonium, but this crystal contains one edge dislocation. Answer the questions.
Figure 2:
If the edge dislocation moves by slip or glide by one unit of b from left to right,
how many bonds will be broken to achieve this outcome?
Answer:
To move the dislocation from its current position (Fig. 2) to the far right (so that a
small step of size b appears at the right-side face), how many bonds will be
broken?
Answer:
Copper at 500 °C has 1.10×1015 vacancies/cm³. The atomic weight of Cu is 63.55 g/mol and the
density at this temperature is 8.96 g/cm³. Avogadro constant NA ~ 6.022×1023 atoms/mol.
Boltzmann constant (K) - 8.62×10-³ ev/atom • K.
(a) What is the activation energy required to create a vacancy in Cu?
(b) Cu is then cooled to 400 °C. What will be the number of vacancies per cubic centimeter?
Assume that the change in the density in the cooling is negligible.
