Abstract
A study of the process of mechanochemical synthesis of titanium nitride under conditions of double mechanical activation of titanium powder: in argon and in nitrogen gas is presented. In the experiments, the time of mechanical activation of titanium in argon and nitrogen was varied. Analysis of the morphology of powder mixtures, X-ray diffraction and microanalysis data showed that preliminary mechanical activation of titanium in argon helps to accelerate 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.
