Abstract: Carbon fiber reinforced steel matrix composites have carbon fiber impregnated in the steel matrix and chemically bonded to the steel. Chemical bonding is shown by the presence of a unique amorphous carbon layer at the carbon fiber/steel interface, and by canting of steel crystal edges adjacent to the interface. Methods for forming carbon fiber reinforce steel composites include sintering steel nanoparticles around a reinforcing carbon fiber structure, thereby chemically bonding a sintered steel matrix to the carbon fiber. This unique bonding likely contributes to enhanced strength of the composite, in comparison to metal matrix composites formed by other methods.

Abstract: The present invention discloses a method of manufacturing, powder making device for rare earth magnet alloy powder, and a rare earth magnet. The method comprises a process of fine grinding at least one kind of rare earth magnet alloy or at least one kind of rare earth magnet alloy coarse powder in inert jet stream with an oxygen content below 1000 ppm to obtain powder that has a grain size smaller than 50 μm. Low oxygen content ultra-fine powder having a grain size smaller than 1 μm is not separated from the pulverizer, and the oxygen content of the atmosphere is reduced to below 1000 ppm in the pulverizer when crushing the powder. Therefore, abnormal grain growth (AGG) rarely happens in the sintering process. A low oxygen content sintered magnet is obtained and the advantages of a simplified process and reduced manufacturing cost are realized.

Abstract: A high-performance permanent magnet is provided. The magnet is expressed by a composition formula: RpFeqMrCutCo100-p-q-r-t. The magnet includes a sintered body including: a plurality of crystal grains each having a Th2Zn17 crystal phase; and a plurality of grain boundaries between the crystal grains. If an oxide phase of the R element is defined by a continuous region that is disposed in the sintered body and contains the R element and oxygen having a concentration of 85 atomic percent or more, a ratio of the number of the oxide phases in the grain boundaries to the number of the crystal grains is 1.1 or less.

Abstract: Methods are provided for producing alloy forms from alloys containing one or more extremely reactive elements and for fabricating a component therefrom. The fabricating method comprises substantially removing a reactive gas from the fabrication environment. An alloy form of the alloy is formed. The alloy form is formed by melting the alloy or by melting one or more base elements of the alloy to produce a molten liquid and introducing the one or more extremely reactive elements into the molten liquid. The molten alloy is shaped into the alloy form. The component is formed from the alloy form. If the one or more extremely reactive elements are introduced into the molten liquid, such introduction occurs just prior to the shaping step.
