Some studies have shown that by combining multiphase magnesium with transition metals and intermetal lic compounds, its hydrogenation kinetics could be improved.

mechanical alloying (MA). MA is a powder metallurgy process that was developed 1960s by the Iin the mid nternational Nickel Company (INCO) as a solid route for introducing and retaining fine refractory oxide particles in high temperature alloys mainly for gas turbine applications [13][15]. It is a solidstate powder processing

Alloying process of mixture of Ti and Fe powders to the TiFe phase was discussed. It was found that synthesis of the CsCltype TiFe phase followed the amorphous phase properties of obtained TiFe alloy were studied.

The present work deals with the synthesis and evaluation of the microstructural and mechanical properties of facecentred cubic Ni Co CrFeTi highentropy alloy strengthened by nanosized titanium oxide dispersion and coherent precipitates of Ni 3 .

Mechanical alloying (MA) is an alternative method and cheapest for the synthesis of this kind of metalceramic materials with respect to the traditional melt and quench process.
