Effects of Microstructural Heterogeneity on the Mechanical Properties of pressed Soft Magnetic Composite Bodies
The elastic and damping properties of two different Soft Magnetic Composite (SMC) materials processed by a powder metallurgy route (SomaloyTM500 + 0.5 % Kenolube and SomaloyTM500 + 0.6 wt % LB1) have been characterised by means of non-destructive resonant vibration analysis, using the Impulse Excitation Technique (IET). Micro-structural characterisation by means of non-destructive (XRD) and scanning electron microscopy (SEM) was carried out in order to understand the structural heterogeneity revealed with IET. A simple structural finite element model confirmed the link between micro-structural heterogeneity of the SMC bodies and their vibration behaviour.
