Abstract
Method of manufacturing magnetically anisotropic permanent magnets consisting of a ni-co-al-ti-cu-fe alloy with a crystalline structure, which is obtained by extracting the heat from the alloy during solidification in a single direction, while, in order to obtain the anisotropy, a heat treatment is carried out in a magnetic field, whose direction coincides with the direction in which the heat is extracted, characterized by the fact that an alloy obtained by technical means in a very pure state with with respect to the elements o, n and c which contains besides iron 28 to 42% of co, 10 to 20% of ni up to 8 of cu and 6 to 10% that al, this last element with a purity of at least 99 8% is added an amount of 4 to 10% of ti of a purity that can be obtained by the known iodide process, and in that during the other steps of manufacturing the magnet from the molten state, the purity obtained is taken into account. With respect to said e is substantially maintained by avoiding reactions of the melt with the atmosphere, the material of the wall of the crucible and the mold, all these measurements being carried out, including the solidification and the heat treatment in the magnetic field, together in such a way that after the final magnetization the magnet has, for a coercivity of more than 1000 oersted a (bh)max of at least 8 x 106, preferably at least 9 x 106 g. Oersted. (Machine-translation by Google Translate, not legally binding)
