摘      要：Non-aligned and aligned polymer-bonded Tb0.3Dy0.7Fe2 composites with 20%particle volume fraction were prepared under different arrangement fields(i.e.0,10 kA/m,20 kA/m,30 kA/m,60 kA/m and 100 kA/m)during their gel *** magnetostriction,dynamic magnetostriction,elastic modulus and compressive strength of all specimens were tested and compared. Experimental results indicate that all the parameters are positively dependent on the arrangement *** dependence is significant at low field levels,the critical value of which is 30 kA/m for the composites *** obvious improvement of the properties can be observed for a larger *** critical values are defined as the optimal arrangement field to manufacture magnetostrictive composites.
