PREPARATION AND PROPERTIES OF FePd ALLOY ULTRAFINE PARTICLES
|
Abstract:
The preparation of FePd alloy ultrafine particles (UFP) by inert gas condensa-tion technique was studied. The properties of the products were measured. The results showthat the composition of the master alloy and the activity coefficient of the components havestrong effect on the products. The single phase uniform alloy UFP can only be obtained byevaporating the alloy with the composition of N_Fe = 0.5. The stability of Fe_(50) pd (50) alloy UFPis higher than that of Fe UFP. The coercivity of Fe_(50)pd_(50), is several times higher than that ofcoarse grain powder with the same composition and can reach the value more than 4.30×10_4 A/m.
