摘要：

The value of the Avrami exponent is changeable in metallic glasses of the same composition. Different populations of pre-existing crystal nuclei correspond to different values of n. With an increase of pre-anneal time, i. e. an increase of pre-existing nuclei, both n and n//t decrease and tend to the value of 3. 0 in the Ni-P amorphous alloy.
