The possible origin of short range atomic displacements coupled with the irreversible amorphous Curie temperature relaxation (Δ TCam) in Fe-based glasses is discussed and analyzed on the basis of quenched-in phase reminiscences. The displacements are dominantly symmetry changes, which are governed by the relative stability of fcc and bcc quenched-in phase reminiscences at a given temperature range. Those of elements which cause positive Δ TCam in as quenched state, also cause positive irreversible Δ TCam during structural relaxation. The influence of Cr addition is just the opposite in this respect.
