EDX elemental analysis of the steel binder in sintered composites from a mechanically activated FeTi + C mixture (BSE-mode) Ta b l e 3 Elemental composition of the steel binder in composites sintered from a mechanically activated FeTi + C mixture (Fig. 4) Number of spectrum Content of elements, at. % Titanium Carbon Iron 5 3.25 46.67 50.09 3 4.15 48.63 47.21 7 7.87 46.80 45.32 For the same reason, when locally determining the elemental composition in the small dark inclusions (fig. 5, Table 4), a lot of iron is detected in the spectra, since the areas in which X-ray radiation is induced exceed the size of the carbide inclusions. In this case, the relative content of titanium and carbon in the spectra corresponds to the composition of non-stoichiometric titanium carbide. The result further confirm that the dark phase in the BSE images is titanium carbide. Fig. 5.
