Abstract: A silicon carbon composite material includes a carbon matrix and a silicon material, the carbon matrix has a cross-linked porous structure internally, and the silicon material is at least partially distributed in the cross-linked porous structure. A value of flexibility C1 of the silicon carbon composite material satisfies 0.4?C1?2. C1 is a factor by which a compression deformation variable of the silicon carbon composite material is scaled to be equal to its rebound deformation variable, representing flexibility of the silicon carbon composite material. When the C1 value satisfies 0.4?C1?2, the silicon carbon composite material has good flexibility, reducing overall impact of expansion stress of silicon on the silicon carbon composite material, and allowing for a certain degree of contractility of the carbon matrix framework, so that residual stress can be received and released, thereby maintaining overall stability of the silicon carbon composite material.

Abstract: The present invention relates to a method for preparing a neodymium-iron-boron rare-earth permanent magnetic material, in particular to a hot press molding-based method for preparing a rare-earth permanent magnet. The problem that the residual magnetism and coercive force of a rare-earth permanent magnet prepared in the prior art cannot be both high is solved. An RTM alloy infiltrates same during an HD treatment. RTM sticks to the surface of coarse powder and infiltrates into the interior of the coarse powder along a grain boundary. The temperature of hot press sintering is relatively low, and grains barely grow. In the absence of Dy and Tb, a higher coercive force is obtained. If an alloy containing Dy and Tb is used for infiltration, these atoms diffuse into the surface layer of a main phase during preheating and heat treatment, achieving grain boundary hardening. Under the premise of a very small reduction in the residual magnetism, the coercive force is greatly improved.
