For investigation of nucleation mechanism of copper precipitates and dislocation loops during neutron radiation, special attention was paid to minor-loop coefficients, which are deduced from simple relations between minor-loop parameters and are very sensitive to lattice defects such as dislocations, copper precipitates, and grain boundaries. We found that with increasing neutron fluence, the minor-loop coefficients of low carbon steel sharply increase and show a maximum at the fluence of 1 ϫ 10 19 cm −2 , followed by a slow decrease. The appearance of the maximum suggests the presence of two mechanisms of internal stress; while copper precipitates and dislocation loops in the matrix make the internal stress increase, those grown in the vicinity of dislocations compensate the internal stress of dislocations so as to minimize the elastic energy. On the other hand, the minor-loop coefficients show a monotonic increase with neutron fluence in Fe metal where dislocation loops play an important role for the brittleness.

“…According to several papers (e.g. [28], [29], [30], [31]), minor loop hystereses can resolve very small differences in magnetic characteristics and/or microstructure. In particular, according to publications [2], [32] and [33], the slope of the hysteresis represents a measure for the magnetic anisotropy, irrespective of reaching saturation or not.…”
