某台国产压水堆压力容器锻件材料断裂韧性韧脆转变的参考温度
The Fracture Toughness Reference Temperature for the Forging of a Homemade Reactor Pressure Vessel
摘要
Abstract
This study experimentally evaluates the use of compact tension specimen(C(T)specimen)to determine the master curve reference temperature,T0 ,for the homemade 508-Ⅲ forging of a homemade reactor pressure vessel.The design for the front face of the C (T)specimen was modified such that the specimen can be conveniently operated in the hotcell for the future testing on the irradiated materials.The results of FEA and experiments using the modified and unmodified C(T)specimens show that the modi-fied design for the specimen would not affect fracture toughness testing.The difference in T0 values be-tween the C(T)specimens and the single-edge notched bend specimens(SE(B)specimen)is approxi-mately 1 ℃.The sections 1.3 and 5.7 of ASTME1921 are discussed.It is concluded that the experimen-tal results support the content of these sections and are close to the average T0 value of the material.关键词
