Mechanical alloying (MA) is a solid-state processing technique allowing production of macroscopically homogeneous materials starting from various powder mixtures. The process is generally carried out in a high-energy ball mill and involves repeated welding, fracturing and rewelding of powder particles. MA is now capable of producing several stable and metastable phases, including supersaturated solid solutions, metastable crystalline and quasicrystalline...
