Abstract
The nature of the inhomogeneities existing in a computer-built model amorphous metal has been investigated by analysing the spatial correlation of various atomic level parameters. It was found that (i) clustering of atomic internal stresses is due mostly to the statistical fluctuation of the random distribution of the atomic level parameter; (ii) spatial fluctuations in the atomic shear modulus, the atomic volume and the geometrical coordination number extend over a longer range (several atomic distances) than was expected from the random distribution; and (iii) the spatial fluctuations of the shear modulus and the atomic volume are quite variable while the stress fluctuation is practically unaltered for the structural change.Keywords
