Milling maps for phase identification during mechanical alloying

Solid state amorphisation in binary systems prepared by mechanical alloying

“…1b and d). Different authors have studied this system [23][24][25][26] and its behavior seems to depend strongly on the milling conditions.…”

Microstructural evolution during mechanical alloying of Mg and Ni

“…Therefore, it follows that the amount of energy put into the system, and also the time necessary to obtain a particular phase, both are function of the BPR. For instance, Suryanarayana et al [28] carried out experiments in SPEX mill using a mixture of Ti-33 at.% Al, obtaining an amorphous phase after 7, 2 and 1 h, using BPRs of 10:1, 50:1 and 100:1, respectively. This relationship between milling time, BPR and phase formation can also be observed in the present study.…”

On the conditions for the synthesis of bulk metallic glasses by mechanical alloying

“…The elemental powder blends of compositions Zr 65 Cu 17 25 Ni 20 have been mechanically alloyed in a high-energy ball mill (Fritsch Pulverisette-P5). The starting elemental powders are of −325 mesh (<45 m) and with purity of about 99.9%.…”

“…For example Burgio et al [23] and Rojac et al [24] have used ball impact energy and cumulative kinetic energy for developing a milling map. Magini et al [22] have used power absorption and degree of filling for a milling map, while Suryanaryana et al [25] have used ball to powder weight ratio (BPR) and milling time in a 2D milling map. Murty et al [17] and Joardar et al [18] have used milling map as an energy map with the impact energy of the ball and the total energy as its axes, which can delineate the energy domain of amorphisation and thus identify the conditions required for amorphisation during MA.…”
