Structure Studies on Mechanically Alloyed Ni₅₀Ti_{50-x}Moₓ (x=10, 25, 40 at.%) Systems during Milling and after Annealing

The subject of this study is the phase composition evolution of Ni50Ti50−xMox (x = 10, 25, 40 at.%) systems prepared by mechanical alloying in as-milled state and after subsequent heat treatment. During milling a mechanically induced solid state reaction between nickel, titanium and molybdenum was observed leading to the formation of nanocrystalline disordered solid solutions. As a result of heat treatment a creation of NiMo intermetallic phase was observed as well as structure relaxation of previously formed solid solutions.
