Virtual instrument to measure the magnetic properties of annealed components

TL;DR: A suitable magnetic fixture that can accommodate test samples of various inner and outer diameters and a virtual instrument that has been developed to perform the comparison method of testing for the annealed samples are presented.
Abstract: This paper presents a new technique based on comparison method of testing to distinguish an annealed magnetic sample from a non-annealed sample of same dimensions. In order to perform this test, a suitable magnetic fixture that can accommodate test samples of various inner and outer diameters has been developed and described in the paper. The paper also gives details of a virtual instrument that has been developed to perform the comparison method of testing for the annealed samples. Using the developed instrument, the samples can be tested after the manufacturing process without any further machining. The performance of the developed instrument has been verified by conducting measurements on different samples of known magnetic properties. The instrument developed distinguished the annealed samples from the non-annealed samples accurately.

TL;DR: In this paper, steel samples cold rolled in two stages with an intermediate annealing were finally annealed in the temperature range 540 −980 −C. Texture improvement on further grain growth resulted in simultaneous decrease of core loss and increase of polarization.

TL;DR: In this paper, Fe30Pd-2Rh (at%) ferromagnetic shape memory (FSM) alloys were forged to a 40-45% reduction in thickness and thermally annealed at 950degC-1000degC for various times to generate recrystallization.
Abstract: Fe-30Pd-2Rh (at%) ferromagnetic shape memory (FSM) alloys were forged to a 40-45% reduction in thickness and thermally annealed at 950degC-1000degC for various times to generate recrystallization. The grain size reduction was observed by scanning electron microscopy (SEM). Investigation with a vibrating sample magnetometer (VSM) revealed that in the strain-forged sample, complete recrystallization contributed high saturated magnetization as well as high magnetic anisotropy. The high magnetic anisotropy improves the magnetostriction of the alloys, which may be useful in magneto-mechanical applications.
