The effects of process control agents on mechanical alloying behavior of a Fe–Zr based alloy

In this work, a Fe–Zr based alloy prepared by MA was investigated. The as-milled powders were characterized using X-ray diffraction, differential scanning calorimetry, induction coupled plasma, chemical analysis and scanning electron microscopy. Analysis shows small contamination (<1.8 at.%) from the milling tools. In MA process, cold welding between particle and particle, and fracturing of the cold welded particles under high energy collision...
