We have found significant differences between the low temperature Miissbauer spectra of rapidly quenched and electrochemically prepared samples in the investigated cases even if the room temperature spectra were similar. In the spectra of electrodeposited alloys a new component appears at low temper

✦ Synopsis
in rewed form I5 Srptrmher 19753 .+bstract-The state of order of a quenched alloy of Ni,Mo was examined by making a systemanc study of electron diffraction patterns taken at a number of poles. These were of both high and low order. chosen to give a full three-dimensional description of the reciprocal unit cell. It was found that all the diffuse maxima in the diffraction patterns could be explained in terms of (I. f. 0: t'pe short-range order (SRO) scattering only.
