Just for cultural value, steel is always crystalline. At one time people
fatigue failures were ascribed to 'crystallization' because the
microcracking associated with fatigue sometimes produced a granular
looking fracture surface. Neither fatigue nor fracture have anything to
do with crystallization. Not meaning to put too fine a point on this, but
fatigue fractures haven't been described as metal crystallization for
quite a while--last time I heard this term (outside the movies) was in
the 50's when the first Comet airliners were having fatigue failures.
