Definitions
- the present invention relates to a process for manufacturing composite 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.
- This boride which is either the diboride AlB 2 , or the dodecaborure AlB 12 , or a mixture of the two is a well defined compound, with great air stability, low volatility, having the advantage of not producing harmful fumes . It can be prepared in various ways known to those skilled in the art and put in the form of particles of average particle size between 5 and 30 ⁇ m coated with aluminum to facilitate wetting and introduction into liquid aluminum.
- the rate of introduction of the boride 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 obtain directly 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 A-S10B 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, it is deduced that the presence of boron does not affect the qualities of the matrix which retains a good part of its properties whether 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 manufacturing of co ⁇ posite alloys from which good resistance to abrasion or friction is expected.
- This composite alloy thus advantageously replaces all mechanically welded or molded fabrications 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 boron.
