摘要: Abstract The ratcheting effect greatly challenges the design of components nuclear power plant. Not only mean stress and amplitude, but temperature also affects strain. In this study, tensile properties Z2CND18.12 stainless steel are studied. relationship between Young’s modulus was studied experimentally. A series experiments under bending loading for were carried out on a dynamic mechanical analyzer. characteristic progressive inelastic deformation material in different temperatures loadings investigated. difference domestic imported experiment results have shown that is better than one properties. linear with change, gradually decreased increase temperature. affect greatly. addition, resistance to at various temperatures. boundary defined based experiments.
