Jones, P. Bonnett, S. Parker] Electrical resistivity and transmission electron microscope studies have been carried out on the primary crystallization process occurring in two batches of the amorphous alloy 2605 CO. The transformation is characterized by an activation energy of ∼ 2.3eV and a pre-exponential constant, InK 0 ∼ 37min−1. The microscope investigations show that the final dendrite size and dendrite volume density (cm−3) are both temperature dependent — moreover the former is also batch dependent. On the other hand the fractional change in resistivity during the anneal seems to be a strong function of final dendrite size and is independent of batch. Observation on partially crystallized samples lends credence to the theory of a rapidly diminishing nucleation rate such that the activation energy of the whole transformation is largely determined by the activation energy associated with the growth of dendrites.
