This chapter reports some fundamental thermodynamic and kinetic aspects of the high-energy ball milling (HEBM) technique. HEBM technology consists in exposing definite quantities of powders to the repeated action of hitting balls, opportunely launched by a BM device.

Improvement of the high energy ball-milling ... - Springer

Ball-milling has been used to prepare performing CO tolerant polymer electrolyte fuel cell anode catalysts that contain Pt and Ru. The catalyst precursors are obtained by milling together Pt, Ru and a dispersing agent in the atomic ratio 0.5, 0.5 and 4.0. This precursor is not easily recovered after milling because it sticks to the walls of the vial and on the grinding balls. However, the ...

Structural changes during high-energy ball milling of iron ...

We report the first study of the effect of high-energy mechanical deformation on amorphous iron-based metallic alloys. The structural changes happening in amorphous iron-based materials containing Co or Ni during mechanical deformation show that the structural stability of an amorphous alloy against a thermal and a mechanical process are not related.
