Abstract:

A quasi-static analysis on 0.30 mm thick Permimphy material has been performed. The samples were mechanically cut as strips with a length of 300 mm and variable widths between 5 mm and 30 mm. The experimental measurements of the normal magnetization curves in quasi-static condition and of the total energy losses as a function of the frequency were made by means of an industrial Brockhaus single strip tester (SST). A hyperbolic model, previously applied in the case of silicon iron steels, was extended for the investigated material and the width of the damaged zone due to cutting procedure was estimated.

Keywords: Nickel based alloys, Energy losses, Static magnetic properties, Hysteresis loss analysis, Normal magnetization curves, Strain-hardening phenomena
