F. Guillet et al., DETERMINATION OF SHORT-DISTANCE ORDER PAR AMETERS IN AN NI2COCR PHASE- PRELIMINARY-RESULTS, Journal de physique. IV, 4(C3), 1994, pp. 59-63
The aim of this work was to characterize the short range order in a ph
ase Ni2CoCr which models the superalloy gamma phase. Anomalous scatter
ing experiments were carried out using the synchrotron beam at LURE-DC
I. The weakness of the short range order signal led us to take into ac
count a more complex analysis technique rather than the usual one. Res
ults show that only the NiCr pair is significantly ordered, the nature
of this order being the same as Ni3Cr (DO22).
