Abstract
Mechanical alloying process and the influence of additives (acetone or ethanol) on the magnetic properties for the mixture of Fe and ZrO2 powders were investigated by mesns of X-ray diffractometer, SEM and VSM. The powder mixtures were milled in vibrating ball mill under Ar atmosphere. In the case of powders without additives, corecive force, He was increased to 16kA/ m with increasing milling time within 100 hours. On the other hand, He of powders with 2% acetone was increased and then decreased with milling time to 7.8kA/m after 170 hours of milling. X-ray diffraction patterns and SEM photographs showed that optimum quantity of addi-tives promote the mechanical alloying of Fe-Zr-O.
