Abstract: The invention relates to a process for casting a sacrificial anode having a tubular steel insert bonded over its length to a dissimilar metal by casting and solidifying molten dissimilar metal on the steel insert in a vertical ingot mold having a movable base. A cooling fluid is passed through a pipe means located internal to the insert, to the level of solidification of the molten dissimilar metal, and the cooling fluid is then applied to the internal surface of the insert at the level of solidification. The level of solidification is raised by the cooling fluid relative to the level without cooling by a height equal to between about 1/4 and 3/4 of the maximum height of molten metal in the mold. The bond strength between the steel insert and the dissimilar metal is improved by this method.

Abstract: An aluminum-titanium-boron mother alloy having a boron content of 0.2 to 0.8% by weight and a titanium content such that Ti - 2.2 B .gtoreq. 3.9%, in which the matrix has a preponderant proportion of grains of less than 30 microns in size, and contains fine TiB.sub.2 crystals having an average size of about 1 micron primarily dispersed along the grain boundaries, and the method for the preparation of same by the formation of titanium diboride by the action of liquid aluminum on titanium oxide and boron oxide in solution in molten cryolite, mixing the reactants in a manner to utilize the starting materials, and then quenching the formed alloy rapidly to cool and solidify the mother alloy, preferably by pouring the liquid alloy in water to produce the alloy in the form of granules or fine powder.
