It follows from experimental observations that ball milling induces substantial changes in an amorphous Co_{70.3}Fe_{4.7}Si_{10}B_{15} (at.%) alloy. X-ray diffraction indicates formation of nanocrystalline bcc-(Co,Fe) phase during ball milling. As a consequence crystallization sequence is altered and the total enthalpy of crystallization reduces with the milling time. Furthermore thermomagnetic measurements reveal that specific magnetization and Curie temperature of amorphous phase are influenced by ball milling.
