在沉淀硬化条件下，在 300 摄氏度、最大剂量为 0.35 dpa 的 17 MeV 质子辐照下，对 Inconel 718 进行扭转蠕变测试。对于 150 至 450 MPa 范围内的所施加剪切应力，辐照蠕变速率的应力依赖性呈线性。讨论了与类似 ITER 机器的操作条件相关的结果，其中使用 Inconel 718 螺栓将屏蔽毯机械连接到背板上。剂量为 0.35 dpa 后，辐照蠕变引起的应力松弛达到约 30%。 (C) 2000 Elsevier Science B.V. 保留所有权利。
Torsional creep tests were conducted on Inconel 718 in the precipitation hardened condition under 17 MeV proton irradiation at 300 degreesC upto a maximum dose of 0.35 dpa. The stress dependence of the irradiation creep rate was linear for the applied shear stresses which ranged from 150 to 450 MPa. The results are discussed in relation to the operating conditions of an ITER-like machine, where Inconel 718 bolts are used to mechanically attach the shielding blanket to the backplate. The irradiation creep induced stress relaxation amounted to about 30% after a dose of 0.35 dpa. (C) 2000 Elsevier Science B.V. All rights reserved.
