| Popis: | Energy absorption properties of offstoichiometric Terfenol-D (Tb(x)Dy(1 − x)Fe2) arcmelted rods were experimentally measured. Samples with Tb compositions for x = 0.35, 0.40, 0.45, 0.50, 0.75 and 1.0 were tested in compression using an MTS load frame under various constant magnetic field conditions. The peak energy absorption occurs at a stress amplitude of 20 MPa for 0.30 ≤ x ≤ 0.50 and shifts to 40 MPa for the Tb compositions of x = 0.75 and 1.0. Combined magnetomechanical loading revealed the influence of magnetic field associated with energy absorption properties. The energy absorption is shown to increase with increasing Tb composition up to x = 0.5. |
