Definitions

  • the present invention relates to a process for the production of coposite alloys based on alloyed or unalloyed aluminum and boron and to its application.
  • the alloy thus produced serves as the master alloy for refining the aluminum, that is to say that it is introduced in very small quantity into the bath to be refined and consequently the problem of its homogeneity is not of paramount importance, because what counts above all is to obtain an average concentration of boron in the bath.
  • French patent 2,231,764 thus claims a process for the manufacture of borated metal products intended for the nuclear industry, characterized in that the metallic material and the boron-based body are in the form of powders, these powders being mixed, pressed and sintered.
  • This process is characterized in that aluminum or an aluminum alloy belonging to the 2000 to 8000 series is used in the liquid state, the metal bath is protected by a deoxidizing flow and maintained with stirring an aluminum boride chosen from diboride, dodecaborure or a mixture of the two at a speed adjusted so as to maintain said bath above its solidification temperature.
  • This boride which is either diboride AIB 2 , or dodecaborure AIB, 2 , or a mixture of the two, is a well-defined compound, with great air stability, low volatility, having the advantage of not producing d noxious fumes. It can be prepared in various ways known to those skilled in the art and put in the form of particles with an average particle size of between 5 and 30 ⁇ m coated with aluminum to facilitate wetting and introduction into liquid aluminum.
  • the boride introduction rate is adjusted so as to keep the aluminum or alloy bath above its solidification temperature.
  • the gas is then degassed under nitrogen or under vacuum and the alloy is quickly poured either into a mold to directly obtain a piece of suitable shape, either in an ingot mold to give a product which is then subjected to at least one of the processing operations such as rolling, forging, spinning, drawing, etc.
  • a composite alloy of the AS10B 3 type was prepared by the process according to the invention which was then transformed by molding into baskets intended for the transport of radioactive materials. Micrographic examination of the alloy showed an even distribution of the boride in the aluminum alloy matrix. Comparative metallurgical tests with normal A-S10, we deduce that the presence of boron does not affect the qualities of the matrix which retains a good part of its properties whether they are physical: density, thermal conductivity, coefficient of expansion, solidification interval; mechanical: resistance and elongation although the latter characteristic is slightly lowered; technological: good aptitude for forging, rolling, drawing, molding, welding, machinability and sealing.
  • the process according to the invention finds its application in the manufacture of composite alloys from which good resistance to abrasion or friction is expected.
  • This compasite alloy thus advantageously replaces all mechanically welded or molded products with borated material insert both from the point of view of ease of implementation and cost price in particular when we make the comparison with borated copper plates or steel racks stainless boré.
