1. A composition comprising:particles of a metallic parent material, and
a mechanical blend comprising a first component and a second component,
wherein the first component is at least one powder of particles of a boron source and wherein the particles in the powders of the boron source have an average particle size less than 250 ?m,
wherein the second component is at least one powder of particles of a silicon source, and wherein the particles in the powders of the silicon source have an average particle size less than 250 ?m,
wherein the mechanical blend comprises boron and silicon in a weight ratio of boron to silicon within a range from about 3:100 wt:wt to about 15:100 wt:wt,
wherein each particle in the mechanical blend is either a boron source or a silicon source,
wherein silicon and boron are present in the blend in at least 80 wt %,
wherein the parent material is less than 75 wt % of the parent material, silicon and boron, and
wherein the at least one boron source and the at least one silicon source are oxygen free except for inevitable amounts of contaminating oxygen, and wherein the inevitable amount of contaminating oxygen is less than 10 wt %.
