  Effect of a quenching medium (water, liquid nitrogen and block of brass) on a
short-range ordering in Fe(100-x)Cr(x) (x less than 19) alloys was studied with
the Moessbauer spectroscopy. The distribution of Cr atoms was expressed in
terms of the Cowley-Warren short-range order (SRO) parameters: alpha1 for the
first neighbor-shell, alpha2 for the second neighbor-shell and alpha12 for both
neighbor-shells. It was revealed that none of the quenching media resulted in a
random distribution of atoms, yet the degree of randomness was the highest for
the samples quenched onto the block of brass. The quenching into water and
liquid nitrogen caused a partial oxidation of samples surface accompanied by a
chromium depletion of the bulk. Quantitative analysis of various phases in the
studied samples both in their bulk as well as in pre surface zones was carried
out.
