3. In a material that can undergo a positional ordering phase transition, is an ordering transition
more likely to occur when the material is cooled rapidly or when it is cooled slowly? Can a
disorder-order phase transition change the lattice structure of a material?
Equations 7.1a and 7.1b, expressions for Burgers vectors for FCC and BCC crystal structures, are of the form
b = uvw)
where a is the unit cell edge length. Also, since the magnitudes of these Burgers vectors may be determined from the following
equation:
1/2
+ v? + w²)"
determine values of |b| for aluminum and chromium. You may want to consult Table 3.1.

Incorrect. Review Section 3.4 and Example Problem 3.1. It may help you to review your homework from Chapter 3.
Review the relationships between the unit cell length and the atomic radius.lf you are having difficulty with this
problem, you may wish to review: Solving Equations, Equations, Symbols and Units, Review of 2D and 3D Geometry.

In XCI, which crystallizes in NaCl structure, the sum of the anionic and cationic radii is found to
be 296 pm. The density of the compound is 4,591 g cm3. Calculate the mass of the cation as g
mol!
Do not write units, only enter numerical values.
Use two digits at most for decimal numbers, use dot (.) as decimal separator
(i.e. two-point-fifty-one should be entered as 2.51). Do not use comma (,) as decimal separator.
