Preparation of duplex phase magnetic materials, which consisted of giant magnetostrictive (Tb_0.5Dy_0.5)Fe_l.8 and zero magnetostrictive Fe-6.5mass%Si alloys was investigated. The giant magnetstrictive (Tb_0.5Dy_0.5)Fe_1.8 powders were synthesized by the mechanical alloying (MA) method. The zero magnetostrictive Fe-6.5mass%Si alloy powders was produced by the water atomization method. The MA was performed in a planetary ball mill. These powders were consolidated at 1273 K. Each powder was filled and sintered in stratified formation in order to make the duplex phase magnetic material. However, the minimum thickness of sintered sample without breaking was 2 mm. To get thinner sintered duplex phases magnetic material, at first only the zero magnetostrictive Fe-6.5mass%Si alloy were sintered. Then the sintered compact was planed the surface to thickness of 0.2 mm. This thin plate was put on the punch in the die. The giant magnetstrictive (Tb_0.5Dy_0.5)Fe_1.8 powders were filled up on this plate in the die to sinter at 1273 K. The thickness of this sintered sample was 0.6mm. The diffusion layer, which is expected as the buffer of the stress produced by bending, -was not observed at the interface.
