Reduction in Hysteresis Loss of Binder Jet Printed Iron Silicon With Boron

Abstract

In this article, we use a factorial design of experiments to develop a three-way relationship between the 3-D printing parameters, the microstructural characteristics, and the hysteresis loss of binder jet printed iron silicon. Subsequent analysis of variance is used to validate the hypotheses between the printing process input factors and the output factors. The input factors in this work include the sintering temperature, the addition of boron, and the silicon content in the starting powder. The magnetic output factors of the printed iron silicon include the intrinsic coercivity and the hysteresis loss per cycle, which are extracted via the use of quasi-static magnetic characterization. Additionally, ac magnetic characterization is used to extract the total iron loss of the binder jet printed silicon. The microstructural output factors are extracted via the use of optical microscope. The established relationship can be used to reduce hysteresis loss in binder jet printed iron silicon.
