摘要：

The magnetomechanical behaviour of Fe-16%Cr-(0-8)%Al and Fe-16%Cr-(0-4)%Mo alloys has been studied over a wide range of frequencies (f = 200-2000 Hz) and deformations (epsilon = 10(-4)-10(-3)). The resonance peaks of the flat beam specimens were recorded from which, several parameters including the damping capacity Q(-1), Delta E effect, internal stress sigma(i) and magnetostriction constant lambda were determined and compared with the permeability and coercivity of samples.
