Abstract

The correlation between the crystallization temperature, crystallization enthalpy and hardness is investigated for Fe-Cr-B amorphous alloys. An inverse relationship has been found between the crystallization temperature and the crystallization enthalpy during host metal replacement by cromium, independent of the boron content. The sudden increase of the crystallization temperature and hardness due to the addition of ∼ 2 at.% Cr indicates the existence of a structural contribution to the mechanism of hardening and stabilization in addition to the well-known compositional effect expressed in terms of the change in the electron concentration.
