In this work two Co_{53.5}Fe_{10}X_{5.5}B_{31} (X = Ta, W) alloys were synthesized from high purity (≥99.9%) powder elements by means of mechanical alloying. In case of Ta-addition, mechanical alloying resulted in formation of two component material with nanocrystalline phase embedded in amorphous matrix. On the other hand, substitution of Ta by W retards partial amorphization induced by mechanical alloying. High pressure-temperature stability of both alloys was monitored using in situ energy dispersive X-rays.
