“…4): the intensity of the both (221) and (002) peaks from the Ti 2 N phase decreased with an increase in soak time to the level comparable with the background after annealing at 550 • C for 100 h or at 750 • C for 10 h. In contrast the (220) maximum of the TiN phase became stronger with the time increasing. This process can be associated with the development of recovery resulting in a reduction in the point defects concentration and, in turn, in a decrease in the stability of the Ti 2 N nitride particles [26,44,45,50]. However, no other evidence of the recovery development was found.…”
