Abstract：The preparation and measurement of the magnetoelastic properties of bonded oriented alloy powder are reported. The experimental results show that the magnetostriction of material is significantly affected by the particle size and compaction pressure, samples with the particle size around 250~420 μm and the compaction pressure of 400 MPa has the largest magnetostriction 870×10-6 without prestressing. By 16-20 kHz magnetic field, the most remarkable factor of material loss is the compaction pressure, the material loss decreases to a lower level when the compaction pressure is higher than 400 MPa.
