Fabrication of tungsten-based metallic glasses by low purity industrial raw materials

▶ W30Fe38B22C10 full metallic glass was successfully produced. ▶ All W30Fe38B32−xCx (x = 7, 10, 13, 15 at.%) amorphous matrix alloys undergo a two-step crystallization with the onset temperature of the first crystallization being as high as 984-1067 K. ▶ Vickers hardness and density values at room temperature are 11.9-12.9 GPa and 14.5 g/cm3 at least, respectively.
