Number Of Factors

The influence of the method of smelting, heat treatment and alloying on the soft magnetic properties of martensite 23Х15Н7М2 tempering steel is investigated. An increase in the soft magnetic properties of steel during smelting in the ДСП-1,5 furnace compared to the ИСТ-0,16 furnace, as well as an increase in magnetic induction and a decrease in the coercive force during heat treatment and the introduction of cobalt into the steel is determined.

AbstractSoft magnetic properties and microstructure evolutions of FeTaNC films were investigated, and compared with those of FeTaN and FeTaC films. Effects of substrate species (glass vs. CaTiO3) on the magnetic properties were also investigated. Co-addition of N and C enhances the grain refinements and soft magnetism compared with N or C only addition. Good soft magnetic characteristics of coercivity of 0.17 Oe, permeability of 4000 (5 MHz), and magnetic flux density of 17 kG can be obtained in the FeTaNC films with the relatively wide process ranges. While these values appear to be similar to those of FeTaN films on glass substrate, the most distinctive difference between FeTaNC and FeTaN (or C) films is the effects of substrate. Whereas FeTaNC films show good magnetic characteristics on both glass and CaTiO3 substrates, FeTaN (or C) films show substantial degradation on the CaTiO3 substrate.

Microscopic Morphology

Fe-based amorphous alloy has excellent soft magnetic properties; traditionally, Fe-based amorphous alloy such as soft magnetic devices was fabricated by insulation enveloping and suppression molding methods. In this process, the aging of organic envelope materials and the crystallization of Fe-based amorphous alloy were usually occurring, accompanying with low magnetic induction and poor mechanical properties. The direct ink writing (DIW) technique can make complex-shaped parts and needs no heating treatment after forming, which can avoid the effect of traditional molding process. In the present study, varying mass fraction FeSiB/EP composite parts were prepared by the DIW technique with the Fe-based amorphous alloy powder and epoxy resin, in which microscopic morphology, magnetic properties, and mechanical properties of FeSiB/EP soft magnetic composites were studied. The results indicate that the slurry with iron powder mass fraction of 92.3, 92.6, and 92.8 wt% has good printing performance and self-support ability, which is suitable for DIW. The density of the printed parts is about 4.317, 4.449, and 4.537 g/cm3, which is almost similar with the iron powder. The tensile strength and elongation of printing parts are significantly improved compared with the pure epoxy resin. From the photos of microscopic morphology of printing parts, it can be seen that FeSiB powders are evenly dispersed in EP, no pores, and defects, with the proportion increasing of powders; the insulation coating thickness decreases; and the magnetic performance improves. The optimal sample is 92.8 wt% FeSiB/EP, in which saturation magnetic induction strength is 137.9759 emu/g and coercivity is 4.6523 A/m.

ABSTRACTIron-carbon based hard, martensitic alloys are usually produced by conventional high temperature heat treatment. In the present work, the galvanostatic electrodeposition method has been employed to obtain hard Fe-0.96 mass % C and Fe-15.4 mass% Ni-0.70 mass% C alloys at around room temperature. The alloys have been investigated by SEM, XPS, XRD, and microhardness measurements, and their magnetic properties have been studied by vibrating sample magnetometer.The as-deposited alloys were found to possess high mechanical hardness, 750-810 HV. Both alloys exhibit a smoother surface morphology as compared to a non-alloyed iron film obtained under similar electrochemical conditions. The coercive force of the as-deposited Fe-C and Fe-Ni-C alloys is 3930 and 494 A.m−1respectively. In comparison, pure iron film deposited under similar conditions possesses a coercive force of 1592 A.m−1. The Fe-Ni-C alloy has a combination of high mechanical hardness and relatively soft magnetic properties, which may be of interest in potential applications requiring both soft magnetic properties and improved tribological performance. The effects of annealing on the behavior of the alloys are discussed.

Optimal Capacity

The soft magnetic properties of Fe-6.5wt.%Si alloy powders produced via high pressure gas atomization under different powder sizes, environments (atmospheric and vacuum) and heat-treatment were presented by vibrating sample magnetometer (VSM), respectively. It is found that the soft magnetic properties of powder gradually grow up as the increasing of the powder size under atmospheric and vacuum environments. However, the using of vacuum environment has an optimal capacity to strengthening the properties rather than atmospheric environment. The heat-treatment of 1000°C for 2 hours offers considerable potential for improving the soft magnetic properties of the powders.
