proton irradiation-induced creep of ultra-fine grain

Materials for Advanced Energy Systems and Fission

Creep deformation under 17 MeV proton irradiation was examined at 288 C for two materials with different levels of cold working (5% and 25%). Tests for 25%CW material were carried out with applied stresses of 170, 270, 370, 470, 570 MPa, and for 5%CW material with 70, 95, 120, 170 MPa.

Whereas the fine-grained aggregates and sutured grain boundaries indicate recrystallization, the palisade grains indicate precipitation from the pore fluid. The twinned coarse calcite grains within the polymict impact breccias are interpreted to be shock induced.

The fine grain size of ODS Mo results in a higher concentration of denuded zones along grain boundaries and improved ductile-laminate toughening that results in improved resistance to irradiation embrittlement for the 600 degrees C irradiations.

Shielding materials in the compact spherical tokamak

The irradiation-induced change in critical current is dependent on the operating temperature. For example, for tapes irradiated to 2 10 22 /m 2 an enhancement is seen at operating temperatures of 50 K or below, and a degradation at higher temperatures [ 9 ].

Proton irradiation

2014/10/1The proton irradiation-induced creep experiments exhibited a linear dependence of creep rate on dose rate, so kE 0 for this work should be independent of dose rate. Three sets of reactor data from Veringa [7], using restrained shrinkage experiments, and two tensile experiments on SM1–24 [18] and IG-110 [19] were plotted along with the proton irradiation results in Fig. 14 .

After irradiation, changes in yield strength, deformation mode, and strain-hardening capacity were seen, with the magnitude of the changes dependent on irradiation temperature. Irradiation to F82H IEA at 573 K led to a significant loss of strain-hardening capacity with a large change in yield strength.

Investigation of the performance of different types of zirconium microstructures under extreme irradiation conditions

Irradiation Induced Grain Boundary Flow—A New Creep

A new mechanism of irradiation enhanced creep is proposed for nanocrystalline materials. It derives from local relaxations within the grain boundaries as they absorb point defects produced by irradiation. The process is studied by inserting point defects into the grain boundaries and following the materials response by molecular dynamics. Calculated creep compliances are found in good
