Mechanical alloying Wikipedia
Mechanical alloying (MA) is a solidstate and powder processing technique involving repeated cold welding, fracturing, and rewelding of blended powder particles in a highenergy ball mill to produce a homogeneous material. Originally developed to produce oxidedispersion strengthened (ODS) nickel and ironbase superalloys for appliions in the aerospace industry, MA has now been shown to
