This report includes the structural materials test results conducted in 1978, such as tensile test, high speed tensile test, creep test, low cycle fatigue test, and relaxation test on structural materials of fast Breeder reactor (FBR). The maximum metal temperatures of the structural materials of prototype FBR components are scheduled 529C for austenitic stainless steels, and 450C for 2 1/4 Cr - 1Mo steel. Under the elevated temperatures as mentioned above, it is necessary to consider the failure modes additionally such as creep rupture, creep fatigue, and creep buckling in case of the FBR component design, therefore, necessary to get a lot of the structural materials test data related to the additional failure modes, especially on creep fatigue and creep deformation behavior under the elevated temperatures. The FBR structural materials test have been started up since 1977 by Structural Material Group, FBR Development Project, Power Reactor and Nuclear Fuel Development Corporation. The Tests conducted in 1978 are as follows: (1)Strength of Base and Pre-strained Metal of SUS304 and Inconel 718 at Elevated Temperature (Toshiba Corp. Ltd.) (2)Strength Tests of Base Metal and Welded Joint of SUS316 and SUS304 Stainless Steel at Elevated Temperature (Hitachi Ltd.) (3)Low Cycle Fatigue, Creep-Fatigue Tests and Stress Relaxation Tests of SUS304 Stainless Steel (Fuji Electric Co., Ltd.) (4)Creep Test of SUS321 Forging and 2 1/4Cr - 1MO Stee1 Plate (Kawasak1 Heavy Industries, Ltd.) (5)Elevated Temperature Properties of SUS321 Heat Exchanger Tube and Forged Thick Plate for LMFBR(Mitsubishi Heavy Industries, Ltd.) (6)A Study on Notch Effeets on Elevated Low-Cycle Fatigue of 304 Stainless Steel(Mitsubishi Heavy Industries, Ltd.) (7)Strength of 2 1/4 Cr- 1Mo Steel and SUS316 Stainless Steel at Elevated Temperature (Babcock-Hitachi K.K.) (8)The Elevated Temperature Properties of SUS316 Heat Exchanger Tubes and Tube-to-Forged Welded Joints and the ...
