Influence of heat of formation of B2/L12 intermetallic compounds on the milling energy for their formation during mechanical alloying

The formation mechanism of mechanically alloyed Fe–20at% Al powder

“…Due to these reasons, mechanically alloyed [10][11][12][13][14][15] and mechanically milled [16][17][18][19][20] Fe-Al alloys of various compositions have been widely investigated. The authors reported the formation of intermetallics [21,22], amorphous phases [13,23], quasicrystalline alloys [24] and extended solid solutions [11,25].…”

Development of a nanostructured Zr3Co intermetallic getter powder with enhanced pumping characteristics

“…Hence, in this system, alloying is initiated by the diffusion of Co in Zr. This hints at the fact that it is difficult to form ZrCo or Zr 2 Co phases from Zr and Co. As a result, ball milling leads to the formation of a Zr rich phase (Zr 3 Co) instead of ZrCo or Zr 2 Co [27].…”

“…This fact accelerates the formation of Zr 3 Co intermetallic phase during heat treatment [27]. Therefore, by controlling the heat treatment conditions (e.g.…”

Planetary Ball Mill Process in Aspect of Milling Energy

“…Joardar et al [30] established the milling criteria for the synthesis of nanocrystalline NiAl by mechanical alloying with changes in long-range order parameter at various milling energies. Abhik et al [31] showed the variation of milling energy required for the start of formation of various compounds with their formation enthalpies. Singh et al [32] attempted to study effect of milling energy on the mechanical activation during the production of MoSi 2 form a reaction of Mo and Si 3 N 4 .…”
