EFI Vim Var Core Iron Soft Magnetic Alloy Rod EFI Vim Var Core Iron Soft Magnetic Alloys 769 Susquehanna Avenue, Franklin Lakes, NJ 07417 • phone 201.891.4003 10537 Humbolt Street, Los Alamitos, CA 90720 • phone 562.431.2568 D ESCRIPTION Carpenter VIM VAR Core Iron is a low carbon magnetic iron produced using vacuum induction melting plus vacuum arc remelting practices. Other elements commonly found in low carbon irons are held as low as possible to ensure good DC magnetic properties. This double melting technique controls the distribution of nonmetallic inclusions to a minimum length and frequency so that thin wall sections will not contain leaks due to internal discontinuities. APPLICATI ONS Carpenter VIM VAR Core Iron is often used in the manufacture of soft magnetic components where vacuum integrity is needed such as in power tubes and microwave devices. In addition, relays, solenoids, and magnetic pole pieces for scientific instru- ments may be made utilizing the qualities of VIM VAR Core Iron. AKA: Carpenter Consumet Core Iron1. Footnotes: 1.

    materials Article Structural, Thermal and Magnetic Analysis of Fe75Co10Nb6B9 and Fe65Co20Nb6B9 Nanostructured Alloys Albert Carrillo, Jason Daza, Joan Saurina, Lluisa Escoda and Joan-Josep Suñol * Department of Physics, Higher Polytechnic School, Campus Montilivi s/n, University of Girona, 17003 Girona, Spain; [email protected] (A.C.); [email protected] (J.D.); [email protected] (J.S.); [email protected] (L.E.) * Correspondence: [email protected] Abstract: Two nanocrystalline ferromagnetic alloys of the Fe-Co-Nb-B system have been produced by mechanical alloying (MA). Their microstructure, thermal behavior and magnetic response were checked by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and vibrating sample magnetometry (VSM). After 80 h of MA, the alloys were nanostructured (bcc-Fe(Co)-rich phase). As the Co content increases, the density of the dislocations decreases. Besides, a higher concentration of Co causes an increase in the activation energy of the crystallization process. The calculated energies, 267 and 332 kJ/mol, are associated to the crystalline growth of the bcc-Fe-rich phase. The Co content of the samples has no effect on the value of the saturation magnetization, whereas the coercivity is lower in the alloy containing less Co. Samples were compacted and heat-treated. Optimal annealing reduces the coercivity by a factor of two. Results were compared with the data of Fe-Nb-B and Fe-Ni-Nb-B alloys.

  • INFLUENCE of PURITY and FABRICATION TECHNOLOGY on the PROPERTIES of SOFT MAGNETIC Fe- 50Ni ALLOY
    U.P.B. Sci. Bull., Series B, Vol. 69, No. 2, 2007 ISSN 1454-2331 INFLUENCE OF PURITY AND FABRICATION TECHNOLOGY ON THE PROPERTIES OF SOFT MAGNETIC Fe- 50Ni ALLOY Violeta TSAKIRIS1, Maria PETRESCU2 Aliajul Fe-50Ni apaţinând grupului de aliaje Permalloy cu aplicaţii în electronică, automatică, telefonie, instrumente electrice fine, a fost elaborat din fier extramoale şi nichel de înaltă puritate (99,95Ni). La elaborare s-a folosit topirea prin inducţie în aer sub protecţie cu insuflare de argon, în locul topirii în vid. Aliajul a fost forjat şi apoi recopt în atmosferă de H2 pentru a obţine o microstructură favorabilă şi o creştere a purităţii chimice şi fizice. Când aliajului forjat i s-a aplicat tratamentul termic de recoacere în H2, s-a obţinut o scădere a durităţii Brinell de la 182 la 130 daN/mm2 şi a câmpului coecitiv de la 0,5 la 0,4 Oe, împreună cu o creştere a permeabiltaţii magnetice de la 16000 la 23000 Gs/Oe şi a inducţiei la saturaţie de la 12300 la 14940 Gs. Luând în considerare creşterea grăunţilor produsă de tratamentul termic de recoacere se poate stabili un paralelism între scăderea de duritate prezisă de teoria dislocaţiilor şi modificarea proprietăţilor magnetice prezisă de teoria câmpului coercitiv. The soft magnetic alloy Fe-50Ni belonging to the Permalloy group that finds application in electronics, automatics, telephony and fine electrical devices has been obtained from extra-mild iron and high purity nickel (99.95). Induction melting was carried out in air under a protective argon blanket instead of vacuum melting. Forging and annealing in H2 atmosphere have been applied for obtaining a favourable microstructure and an increase in chemical and physical purity.

Postal: 68503, Rio de Janeiro, RJ, 21941-972, Brazil [email protected] Abstract. Developing a new material or even improving properties of an existing material is a complex and time- consuming task. In recent years, materials scientists around the globe proposed a number of ways to speed up the alloy development process by using various computational tools. In this work, we made an attempt to demonstrate the efficacy of using computational tools in design optimization of materials, especially for high-temperature applications. We addressed two different material systems: Alnico alloys (magnetic) and Nickel-based superalloys. Alnico type alloys are hard magnetic alloys and well known for high-temperature applications. In this work, we defined the variable range of various elements and generated an initial set of alloys by a quasi-random sequence generation algorithm. These alloys were synthesized and tested for determining various material properties. We used a response surface methodology approach to develop surrogate models (meta-models) that approximately linked alloy chemistry with desired properties for these multi-component systems while being computationally affordable. These models were further used for multi-objective optimization of desired (conflicting) properties by using a number of algorithms based on evolutionary approaches, as well as our hybrid optimizer.

Shaw Lane, East Lansing, MI 48824, USA. Abstract: Additive manufacturing has many advantages over traditional manufacturing methods and has been increasingly used in medical, aerospace, and automotive applications. The flexibility of additive manufacturing technologies to fabricate complex geometries from copper, polymer, and ferrous materials presents unique opportunities for new design concepts and improved machine power density without significantly increasing production and prototyping cost. Topology optimiza- tion investigates the optimal distribution of single or multiple materials within a defined design space, and can lead to unique geometries not realizable with conventional optimization techniques. As an enabling technology, additive manufacturing provides an opportunity for machine designers to overcome the current manufacturing limitation that inhibit adoption of topology optimization. Successful integration of additive manufacturing and topology optimization for fabricating magnetic components for electrical machines can enable new tools for electrical machine designers. This article presents a comprehensive review of the latest achievements in the application of additive manu- facturing, topology optimization, and their integration for electrical machines and their magnetic components.

The amorphous method was used to prepare iron with the best amorphous thin strip processing parameters: the size of circular quartz tube was 0.8 mm; the distance between the nozzle and the surface of copper roller was 0.5 mm; the linear speed of copper roller surface was 41 m/s; the pressure difference between the inside and outside of quartz tube was 0.03 MPa; the spray angle was 0°. The solidification of the Fe based nanocrystalline alloy was studied by the solidification morphology, X-ray diffraction analysis, magnetic properties and mechanical properties. According to EIS studies, a 360K undercooling temperature leads to an increase in the penetration of electrolyte ions into electrode structures due to the formation of a high surface area and a high electron-transfer rate. The experimental results show that the undercooling of the alloy melt can be significantly improved by the amorphous method; the crystallization process of the prepared nanocrystalline alloy was controlled by the growth of the nanocrystalline; the prepared Fe based nanocrystalline alloy was more suitable for the common mode choke core, and can reflect different degrees of magnetic properties under the influence of different annealing temperatures; the prepared Fe based nanocrystalline alloy was better than the coarse-grained alloy.

    magnetochemistry Review Laser Additive Manufacturing of Fe-Based Magnetic Amorphous Alloys Merve G. Ozden * and Nicola A. Morley Department of Material Science and Engineering, University of Sheffield, Sheffield S1 3JD, UK; n.a.morley@sheffield.ac.uk * Correspondence: mgozden1@sheffield.ac.uk Abstract: Fe-based amorphous materials offer new opportunities for magnetic sensors, actuators, and magnetostrictive transducers due to their high saturation magnetostriction (ls = 20–40 ppm) and low coercive field compared with polycrystalline Fe-based alloys, which have high magne- tostriction but large coercive fields and Co-based amorphous alloys with small magnetostriction (ls = −3 to −5 ppm). Additive layer manufacturing (ALM) offers a new fabrication technique for more complex net-shaping designs. This paper reviews the two different ALM techniques that have been used to fabricate Fe-based amorphous magnetic materials, including the structural and magnetic properties. Selective laser melting (SLM)—a powder-bed fusion technique—and laser- engineered net shaping (LENS)—a directed energy deposition method—have both been utilised to fabricate amorphous alloys, owing to their high availability and low cost within the literature. Two different scanning strategies have been introduced by using the SLM technique. The first strategy is a double-scanning strategy, which gives rise to maximum relative density of 96% and corresponding magnetic saturation of 1.22 T. It also improved the glassy phase content by an order of magnitude of 47%, as well as improving magnetic properties (decreasing coercivity to 1591.5 A/m and increasing magnetic permeability to around 100 at 100 Hz). The second is a novel scanning strategy, which Citation: Ozden, M.G.; Morley, N.A.
