Fine Alnico 8 spherical powder produced by gas atomization was consolidated through hot pressing (HP), hot isostatic pressing (HIP), and compression molding and subsequent sintering (CMS) techniques. The effects of different fabrication techniques and processing parameters on microstructure and magnetic properties were analyzed and compared. The HP, HIP, and CMS magnets exhibited different features...
In this paper, the effect of different preparation process on the secondary electron emission performance was investigated. The different doping methods and preparation techniques such as Solid-Solid doping(SS), Liquid-Solid (LS) doping, Liquid-Liquid (LL) doping, Spark Plasma Sintering (SPS), Air Plasma Spray (APS) method, were introduced into this kind of materials. The microstructure of samples...
This paper studies the preparation procedure of nanostructured (LaxBa1-x)B6 cathode materials by liquid phase reactive spark plasma sintering. The phase identification and purity of the sintered samples is determined by X-ray diffraction (XRD) and X-ray fluorescence. The vibrational property is examined by using Raman spectroscopy. The SEM and electron back-scattered diffraction (EBSD) investigation...
In this paper, a study on quick spark plasma sintering (SPS) method for synthesizing the polycrystalline CeB<;sub>6<;/sub> bulk is presented. CeB<;sub>6<;/sub> is the material of choice for high current density cathode. However, in fact, because of the long sintering time and high temperature, the traditional hot pressure sintering preparation of polycrystalline CeB<;sub>6<;/sub>...
