Radiation-induced segregation in austenitic stainless steel type 304: Effect of high fraction of twin boundaries

On the role of residual strain in controlling sensitisation of twin-boundary engineered type 304 stainless steel

“…To evaluate sensitisation behaviour, specimens were given two potential sensitisation treatments at 575°C for 1 h (referred as S1) and 675°C for 1 h (referred as S2) in air, followed by water quenching. Similar type of experimentation for the as-received material (A0) had already been reported [42]. Different specimens are referred to indicate a combination of solution-annealing and strain-annealing treatment.…”

“…The combined effect of residual-strain and high fraction of special boundaries on sensitisation in GBE austenitic SS is investigated. In a previous study [42], specimens of type 304 SS (in the asreceived condition) with prior cold-work were subjected to a 5% strain followed by strain-annealing at different combinations of time and temperature. In the present investigation, the AR material was given two solution-annealing heat-treatments to reduce the level of prior cold-work and to increase the grain size.…”
