ABSTRACT:
A process for making a boron alloy from a ferrous or non-ferrous melt by adding a boron compound to the melt and reducing the compound within the melt by a reductant, such as aluminum, silicon or carbon, such that the boron can alloy with the melt. A boron alloy containing from very little boron up to 15% boron by weight can be formed. At least 40% of the boron compound is reduced to boron.
The alloy can also be employed to make an amorphous material by discharging the molten alloy onto a moving surface to form a strip. The moving surface is a chill body which can quench the strip at a rate of at least from 10.sup.4 .degree. C./sec, or higher to solidify the strip and form an amorphous boron alloy material.
