Comparison of fission neutron and proton/spallation neutron irradiation effects on the tensile behavior of type 316 and 304 stainless steel

The tensile properties of AISI 316L and OPTIFER in various conditions irradiated in a spallation environment

“…Recently such comparison between spallation and fission irradiation for 316L with more complete data was given in Ref. [10]. The general trend is similar as we find hear.…”

Effect of irradiation-induced plastic flow localization on ductile crack resistance behavior of a 9%Cr tempered martensitic steel

“…Above about 1 dpa, plastic instability becomes evident, characterized by a premature necking occurring shortly after the yield strength is reached. This observation is typical of many materials experiencing dislocation channel deformation [6,9,[12][13][14][15]29,[41][42][43][44][45][46][47].…”

Plastic instability behavior of bcc and hcp metals after low temperature neutron irradiation

“…Although the channel deformation frequently coincides with a reduced strain-hardening rate or a prompt necking at yield [1][2][3][4][5][6][7][8][9], it has not been explicitly demonstrated that channel deformation directly causes prompt necking at yield. Fig.…”

“…Metallic materials often experience a complete loss of uniform ductility, or prompt necking at yield, after low temperature irradiation [1][2][3][4][5][6][7][8]. The low temperature irradiation usually results in a strong radiation-induced hardening as well as in a reduction of strain-hardening rate, and both of these radiation effects can cause the loss of uniform ductility [3][4][5][6][7][8][9].…”
