ABSTRACT:
Boron-containing transition metal alloys based on one or more of iron, cobalt and nickel, and containing at least two metal components, are characterized by being composed of ultrafine grains of a primary solid-solution phase randomly interspersed with particles of complex borides which are predominantly located at the junctions of at least three grains of the primary solid-solution phase. These alloys are obtained by devitrification of the solid, amorphous state under specific heat-treatment conditions. These alloys can be consolidated into three-dimensional bodies.
