Abstract

The changes of short range ordering and electron density were investigated by nuclear gamma-resonance and positron annihilation methods in model alloys containing tungsten, chromium, molybdenum, and vanadium used as doping additions. The change of the short-range ordering parameter sign was detected in alloys containing vanadium used as dopants.. Different ordering was also observed in binary and ternary iron alloys. It was shown that dislocations were the basic defects in materials after rolling.
