چکیده انگلیسی
ⶠA part of AlN was found to be gradually reduced by Ti during MA and Ti(Al,N) solid solution formed after early stages of milling. ⶠThe particle size of supersaturated Ti(Al,N) solid solution and AlN reduced to submicron size and nanocrystalline structure as evident from XRD and SEM results. ⶠThe lattice parameter and interplanar distance of Ti shows that all of the decomposed Al dissolved in the Ti lattice by MA and causes its contraction, while only 1 at.% of N dissolves to form Ti(Al,N) solid solution and leads to its dilation and the remaining N reacts with Ti to form TiN. ⶠAnnealing of 360 ks MA powder leads to phase transformation as a result of increased thermal diffusivity, the formation of more TiN phase with more under-stoichiometric characteristic, as well as stress releasing and grain growth.
