Mechanical properties and stability of precipitates of an ods steel after thermal cycling and aging
Nuclear Materials and Energy(2020)
摘要
•No changes in mechanical strength after thermal cycling or aging.•High stability of Ti-rich oxides.•Chemical evolution and redistribution of Cr-W-rich precipitates along grain boundaries.•Loss of ductility after thermal aging attributed to grain boundary embrittlement.
