Free for commercial use High Quality ImagesSep 1, 2016 · This paper presents a calculation method of residual magnetic flux density distribution for a four-pole anisotropic bonded NdFeB permanent magnet (PM) considering the effect of aligning magnetic field during the forming process. To manufacture the anisotropic bonded NdFeB magnet, the magnet powder needs to be aligned with a proper aligning field before magnetizing. Therefore, it is necessary ... Isotropic and anisotropic NdFeB permanent magnets were prepared by Spark Plasma Sintering (SPS) and SPS followed hot deformation (HD), ... The magnetic properties of hot pressed and die-upset forged Fe-RE-B magnets made from melt spun ribbons are studied in relation to the microstructure of the initial ribbon.The pressless process (PLP) is a kind of near net-shape manufacturing technique. The initial production of the pressless process (PLP) magnet is very close to final shape, therefore reducing machining and grinding cost dramatically. The shape and dimensions of the final magnet, and shrinkage degree of the NdFeB powder after …Textured NdFeB HDDR magnets Figure 5.

Nov 1, 2017 · The method combines hydrogen decrepitation (HD) disintegration of the initial magnet, powder sieving and the Press-Less Process (PLP), where hydride powder is sintered in a graphite mold. Coercivities up to 534 kA/m were obtained in porous samples based on powder size d < 100 µm. Adding a ball milling step resulted in full density isotropic ... Oct 9, 2012 · Pressing methods used to make sintered magnets. Note that in isostatic pressing, the part is aligned in a separate processing step, prior to pressing. Source: Vacuumschmelze catalog. In some cases, I have seen designs with both NdFeB and SmCo options. Similarly, it makes sense to look at both bonded and sintered NdFeB solutions. 1.

Looking to reduce video file size?Apr 1, 2006 · With the highest hard magnetic properties, widespread application and rapid development, NdFeB magnets have been called the new generation of permanent magnet. The theoretical value of energy product of NdFeB can reach as high as 65 MGOe [1]. The experimental value of energy product of NdFeB has reached 56 MGOe [2]. The coercivity and remanence ... Oct 15, 2019 · The c-axes of these grains are parallel to the pressing direction [8], [9]. The alignment and microstructure of hot-deformed magnets are determined not only by the raw melt-spun ribbons, but also by the process routes. Because nanocrystalline is very sensitive to process parameters such as temperatures for hot pressing and hot deforming. deformed (HDed) NdFeB magnets, good magnetic properties together with exceptional corrosion, thermal stability, and fracture toughness can be obtained [1–4]. It is well known that the grain of HDed NdFeB magnets (by die-upsetting or extruding) is elongated normal to the press direction, is platelet-shaped and oriented in such a way …Jun 4, 2021 · The Nd-Fe-B magnets right after the sintering process show a very small coercivity of ~0.8–0.9 T. After annealing the as-sintered magnets at ~520–600°C, coercivity increases by ~25–30% [ 8–20 ]. Typical microstructure of Nd-Fe-B sintered magnets, shown in. Figure 1. The corrosion behavior of hot-pressed nanocryst. NdFeB magnet in a NaCl-induced atm. with relative humidity of 80% was investigated using SEM/EDS and XPS techniques. The NaCl deposits significantly increased the initiation and development of the corrosion of NdFeB, esp. that of Nd. During corrosion process, Nd2Fe14B decompd. into several …Then, the powder was cold-pressed at room temperature followed by hot-pressing at approximately 800°C to obtain a fully dense body. A hot-pressed body is an isotropic magnet with grains that are approximately 20–50 nm. ... Microstructure of hot-pressed and die-upset NdFeB magnets. J Appl Phys. 1987; 62 (3):967–971.
