An equation, describing crystallization kinetics, of the form:
where is the crystalline volume fraction developed at time
and constant temperature,
and
are suitable parameters.
is temperature dependent. According to the original theory, should be an integer from 1 to 4, the value of which should depend only on the type
of the statistical model; however, it has become customary to regard it as an adjustable
parameter that may be non-integral.
