摘要： A system is capable of making a metallic product with robust mechanical and electrical properties. The system includes a pressing stage configured to compress powder (e.g., MMC material) to form a green compact from the powder, a sintering stage configured to sinter the green compact to form a sintered structure from the green compact, and a consolidation stage configured to apply electric current to the sintered structure to form the metallic product from the sintered structure. The electric current is in the form of high density, short electric AC or DC pulses and results in consolidation of the sintered structure at grain boundaries to correct defects in the boundaries (e.g., areas of high electrical resistance) without melting the bulk metal to produce the metallic product. Such a system alleviates the need for coining process, which could fracture bonds and thus weaken the structure, following the sintering process.

摘要： The objects of the present invention are to provide a durable magnetic field molding device for producing molded bodies for ferrite magnets, which needs a controlled amount of releasing agent, reduces production cost and improves productivity, and die and magnetic field molding method. The lower die 12B of the die 12 is coated, on the surface which defines the cavity 11, with the coating film 30 with a high hardness and a low friction coefficient, which improves resistance of the lower die 12B surface to wear by the solid component (fine powder) in the slurry, thereby greatly improving durability of the coating film 30 itself and reducing lubricant usage.

摘要： The invention concerns a block fuel element consisting of only one carbon matrix which is almost isotropic of high crystallinity into which the coated particles are incorporated by a pressing process. This block element is produced under isostatic pressure from graphite matrix powder and coated particles in a rubber die and is subsequently subjected to heat treatment. The main component of the graphite matrix powder consists of natural graphite powder to which artificial graphite powder and a small amount of a phenol resin binding agent are added.

摘要： Method and device for protection against thermal shocks on refractory materials which are not very conductive, such as ceramic substances, intended to be brought repeatedly into contact with very corrosive melted substances such as aluminium. Slots having no great depth, rounded off at their ends, are formed at the surface of the substances put into contact with the molten metals. Those slots are stuffed with compacted ceramic fibres which are impermeable to the molten metals. Application is to the protecting of the body of conduction pumps immersible in liquid aluminium.

摘要： The invention relates to a heat transfer element made of a polymer matrix having a fibrous material interspersed therein, said heat transfer element comprising a fluoropolymer at least on an outer surface thereof, the interspersion of the fibrous material within the polymer matrix providing rigidity to the heat transfer element, a thermally conductive material being distributed within the heat transfer element. Such a heat transfer element can be used in the manufacture of radiant panels for power generating stations or can be formed as a pipe for similar use. The heat transfer element may comprise a polymer sheet having a fibrous material distributed therein providing structural strength and a fluoropolymer at least on an outer surface of the element which protects the element from physical and chemical corrosion whilst providing anti-fouling properties and good flow characteristics to the element. A thermally conductive material is distributed within the element to provide the necessary heat transfer characteristics.
