Abstract

The invention belongs to the technical field of irradiation measurement, and particularly relates to an irradiation on-line internal friction in-situ measurement device. The device comprises a sealed vacuum chamber (1) provided with a heavy ion beam pipeline (9), the interior of the vacuum chamber (1) is used for arranging an irradiation sample (12) and can heat the irradiation sample (12), an accelerated heavy ion beam can irradiate the interior of the irradiation sample (12) through the heavy ion beam pipeline (9), and the device further comprises a displacement detector (7) used for measuring the displacement change of the irradiation sample (12). The device realizes on-line in-situ measurement of the mechanical property of the material in a heavy ion irradiation experiment in a high-temperature environment, can visually obtain the change of the mechanical property of the material by measuring an internal friction spectrum in the irradiation process, and obtains the type, concentration and dynamic diffusion process of irradiation defects generated in the material irradiation process, and information of irradiation embrittlement, defect evolution and the like of the material under irradiation conditions such as temperature, irradiation dose and the like is obtained.

Description

technical field [0001] The invention belongs to the technical field of radiation measurement, and in particular relates to an in-situ measurement device for radiation on-line internal friction. Background technique [0002] In the new generation of nuclear energy systems, the conventional working temperature of structural materials is 300-1000°C, and at the same time they are irradiated by neutrons with a radiation damage dose of 100-200dpa or higher. Therefore, one of the most important failure modes of structural materials in the reactor is High-temperature and high-dose radiation damage and the resulting decline in comprehensive performance. Radiation damage not only affects the service life of structural materials in the reactor, but is also directly related to the safety of the reactor, which is also a problem that must be considered and studied in the research and development of reactor structural materials. [0003] In addition to good radiation resistance, corrosion...
