[1M11] Study on micromechanics in duplex stainless steels for long term operation of nuclear power plants
キーワード：Duplex Stainless Steels, Thermal Ageing , Irradiation , Nanoindentation
In this study, to develop more universal degradation model for DSSs, the effects of thermal ageing and irradiation on microscopic hardness in both ferrite and austenite in various DSSs following thermal ageing or irradiation is carefully examined using nanoindentation technique.The ralationship between macroscopic and microscopic hardness of samples, the microscopic hardness of materials has been expected.
