Correlating CSL Evolution and Strain Energy in Single Step Grain Boundary Engineered Austenitic Stainless Steel

Correlating CSL Evolution and Strain Energy in Single Step Grain Boundary Engineered Austenitic Stainless Steel

Coincident site lattice (CSL) boundary evolution was investigated in 316LN SS subjected to single step thermomechanical treatment (TMT). Four different TMT processes constituting prior cold work (PCW) up to 5 pct and post annealing treatments up to 1273 K were examined. Remnant strain energy in each...

Zusammenfassung:Coincident site lattice (CSL) boundary evolution was investigated in 316LN SS subjected to single step thermomechanical treatment (TMT). Four different TMT processes constituting prior cold work (PCW) up to 5 pct and post annealing treatments up to 1273 K were examined. Remnant strain energy in each TMT condition was calculated using Kernel Average Misorientation (KAM). Prevalence of strain-induced boundary migration (SIBM) being an underlying mechanism for CSL generation was examined using estimated remnant strain energy.
