“…The main difference is that the martensite phase was no longer found in this specimen. Morisawa et al [18] reported that elongation decreased with an increase of magnetic flux density and that interganular cracking appears. The transition of the martensite phase can be responsible for the significant drop in intergranular cracking after annealing.…”

“…However, it has been reported that magnetization of the steel, caused by the transformation from austenite to martensite, can be induced along grain boundaries by chromium depletion [17]. Moreover, Morisawa et al [18] reported an increase of magnetic flux density with neutron fluence in irradiated type 304 stainless steel.…”

“…Formation of magnetic phases in 300-series steels has been observed and reported by numerous authors for a wide range of irradiated Fe-Cr-Ni steels and alloys by using magnetic properties [29][30][31] and by microscopy [32,33]. The formation of radiation-assisted ferrite has been observed in specimens irradiated at the operational temperature of power reactors [34,35] and…”

Please cite this article as: M.N. Gussev, D.A. McClintock, F.A. Garner, Analysis of structure and deformation behavior of AISI 316L tensile specimens from the second operational target module at the AbstractIn an earlier publication, tensile testing was performed on specimens removed from the first two operational targets of the Spallation Neutron Source (SNS). There were several anomalous features in the results. First, some specimens had very large elongations (up to 57%) while others had significantly smaller values (10-30%). Second, there was a larger than the usual amount of data scatter in the elongation results. Third, the stress-strain diagrams of nominally similar specimens spanned a wide range of behavior ranging from expected irradiation-induced hardening to varying levels of force drop after yield point and indirect signs of "traveling deformation wave" behavior associated with strain-induced martensite formation. To investigate the cause(s) of such variable tensile behavior, several specimens from Target 2, spanning the range of observed tensile behavior, were chosen for detailed microstructural examination using electron backscatter diffraction (EBSD) analysis. It was shown that the steel employed in the construction of the target contained an unexpected bimodal grain size distribution, containing very large out-of-specification grains surrounded by "necklaces" of grains of within-specification sizes. The large grains were frequently comparable to the width of the gauge section of the tensile specimen. The propensity to form martensite during deformation was shown to be accelerated by radiation but also to be very sensitive to the relative orientation of the grains with respect to the tensile axis. Specimens having large grains in the gauge that were most favorably oriented for production of martensite strongly exhibited the traveling deformation wave phenomenon, while those specimens with less favorably oriented grains had lesser or no degree of the wave effect, thereby accounting for the observed data scatter.

“…Due to the ferromagnetic nature of the strain-induced ␣ martensite, magnetic methods have been widely studied [6][7][8][9]. Among them, the magnetic Barkhausen emission (MBE) method is very powerful due to its double sensitivity, on one hand to the fraction of phase transformed [3,10,11] and on the other hand to the residual stress left in the martensite [11,12].…”
