ABSTRACT:
A homogeneous boron containing alloy is disclosed with a composition which can be essentially represented by the formula of: M.sub.i T.sub.j B.sub.k where M is a metal from the group of nickel, iron, cobalt or a mixture thereof; T is a refractory metal from the group of molybdenum, tungsten, or a mixture thereof; and B is the element boron. The subscripts i, j, k are the respective atomic percent of each of the constituents and vary respectively between about 25 and 98, between about 1 and 40, and between 1 and 35 with the proviso that j>k, and i+j+k=100. By further limitation of the chemistry, it is possible to assure the alloy will age harden.
