| Abstract Scope |
Solid and lattice rods of Fe<sub>81</sub>Al<sub>19</sub> were additively manufactured using the laser powder bed fusion technique. Magnetic and magnetostrictive properties were measured as a function of applied magnetic field under various applied compressive stresses. Magnetostriction of the lattice rods was measured using laser Doppler vibrometry. Both the solid and lattice rods exhibited approximately the same magnetostriction values, although their values were lower than expected. The elastic modulus and the yield stress of the rods was highly dependent upon the laser parameters used, exhibiting worse properties with the higher laser scan speed of 1.5 m/s. Young’s modulus increased by a factor of 1.6 (from 53 to 85 GPa), and the yield stress increased by a factor of 1.7 (from 148 to 248 MPa) by decreasing the laser speed. The yield stress was still lower than for a bulk sample, mainly due to internal porosity, indicated by the rather pebbly fracture surface. |
