Study of alloying mechanisms of ball milled Fe–Cr and Fe–Cr–Co powders

Structure, magnetic and Mössbauer studies of mechanically alloyed Fe–20wt.% Ni powders

“…The same authors [34] showed that the average hyperfine field B is less than 30 T when the composition of the Cr is up to 30% Cr. Bentayeb et al [35] have found that for Fe-Cr 31 , the value of B is closed to 26 T. In our case let us remember that the contamination of the Cr composition is less than 1%.…”

Amorphisation of Cr–10Co mixture by mechanical alloying

“…For example, the contamination by oxygen and nitrogen during mechanical alloying of Cr and Fe gives rise to an amorphous phase in spite of its small mixing enthalpy (DH = À1 kJ mol À1 atom À1 ) [4]. However, in the absence of such gases only intermetallic phases are produced [5,6]. A similar situation can be obtained for mechanically milled Ni-Nb system [7].…”

Partial amorphization of an α-FeCr alloy by ball-milling

“…The behaviour under ball milling of α and of σ FeCr phases was for instance studied in nitrogen, in argon and in vacuum [7][8][9][10][11][12][13][14][15]. Besides the alpha phase, an amorphous phase appears when milling the σ phase for times longer than 20 h in mild conditions in a vibratory mill in argon and in vacuum [14,15].…”
