Titanium Nitride Synthesis during Double Mechanical Activation of Titanium—in Argon and in Nitrogen

The mechanochemical synthesis of titanium nitride during double mechanical activation of titanium powder is studied in argon and in nitrogen gas. The duration of mechanical activation of titanium in argon and nitrogen is varied in experiments. As suggested by the analysis of powder mixture morphology, X-ray diffraction analysis, and microanalysis, the preliminary mechanical activation of titanium in argon contributes to accelerating the mechanochemical synthesis of titanium nitride. Analytical relationships are obtained and theoretical estimates are given that make it possible to predict the process of double mechanical activation of titanium.
