<p>'A wear-resistant, iron-molybdenum boride alloy is disclosed as is a method of making it. The alloy has a microstructure comprising a primary boride phase and a matrix phase. The primary boride phase comprises molybdenum alloyed with iron and boron, and the matrix phase comprises one of iron-boron in iron and iron-molybdenum in iron and has a hardness less than that of the primary boride phase. The subject alloy generally has an average hardness level above 1550 Kg/mm<Sup>2</Sup> Knoop to 500 gram load finds particular utility in a composite material on a ground-engaging tool such as a cutting edge or ripper tooth, and can also be used for wear-resistant coatings, machine tool inserts, bearings, and the like.</p> |
