Mechanical alloying (MA) creates advanced Mg-Ti alloys via controlled microstructural changes and uniform elemental distribution. High-energy ball milling induces solid-state reactions, refining alloys. Parameters like duration, ball-to-powder ratio, and speed impact microstructure. Analytical tools reveal phase changes, microstructural evolution, and element distribution. Mg-Ti alloys exhibit enhanced mechanical properties. MA shows promise for aerospace and automotive applications, with challenges to address for full potential realization. This chapter discusses the different approaches opted for mechanical alloying of magnesium and titanium alloys.
