| Abstract: | Conclusions A study was made of some key physicomechanical properties of iron-boride materials alloyed with Nb, Mo, and W. The greatest strengthening effect ( t = 62–75 kgf/mm2 at 30–33 HRC) is achieved with iron-tungsten matrices infiltrated, using alloyed powders produced by coreduction from oxides, with eutectic Fe-Mo-B or Fe-Nb-Mo-B alloys. The presence of Fe(Nb, Mo)xBy type borides in the eutectic alloys substantially increases the heat resistance of the infiltrated materials.Translated from Poroshkovaya Metallurgiya, No. 2(206), pp. 79–82, February, 1980. |
