Синтез Ti2Ni методом механического легирования

Abstract

It has been studied a synthesis of Ti2Ni by the method of mechanical alloying and annealing of powders. The average size of the powder particles measured by SEM decreases from 15,7 µm to 9,6 µm at 7 % mass. Ti and increases to 19,2 µm at 25 % mass Ti. Mechanical alloying and annealing of powders lead to the formation of the main Ti2Ni phase. The lattice parameter of the Ti2Ni phase decreases with increasing titanium content from 1,1294 ± 5 · 10-4 nm to 1,1251 ± 5 10-4 nm. The CDD size of the Ti2Ni phase is 53 ± 10 nm.
