Mechanical alloying

<p>Mechanical alloying (MA) is a solid-state and powder processing technique involving repeated <a href="/facts/Cold_welding/30B1C0Wg">cold welding</a>, fracturing, and re-welding of blended powder particles in a high-energy <a href="/facts/Ball_mill/40Xn4KUQ">ball mill</a> to produce a homogeneous material. Originally developed to produce <a href="/facts/Oxide-dispersion_strengthened/BwSz4gAq">oxide-dispersion strengthened</a> (ODS) nickel- and iron-base <a href="/facts/Superalloy/UwshApNV">superalloys</a> for applications in the aerospace industry, MA has now been shown to be capable of synthesizing a variety of equilibrium and non-equilibrium alloy phases starting from blended elemental or pre-alloyed powders. The non-equilibrium phases synthesized include supersaturated solid solutions, metastable crystalline and quasicrystalline phases, nanostructures, and amorphous alloys.The method is sometimes is classified as a surface <a href="/facts/Severe_plastic_deformation/LIzE15Uq">severe plastic deformation</a> method to achieve nanomaterials.
