|Abstract:||The present study was aimed to prepare a material which combines a high magnetostrictive strain in low magnetic fields with a high mechanical strength. Therefore we prepared composites which consist of soft magnetic Fe77Al2.4P8.64C5B4Si2.6Ga0.8 and high magnetostrictive (Fe2Sm) alloys. Ball milling of the amorphous FeAlPCBSiGa ribbon and a crystalline Fe2Sm ingot and subsequent hot pressing of the resulting powders were used to prepare disc shaped composites. A maximum magnetostrictive susceptibility of 930 ppm T-1 at a field of µ0H = 0.1 T was obtained. The hardness varied from 150 HV10 to 340 HV10 with increasing amount of the amorphous phase.|
