    The value of the recoverable strain is comparable to that observed under the conditions of the shape memory effect on heating of the deformed alloy and even somewhat exceeds it. The obtained data show that neutron irradiation can induce the shape-memory effect in the TiNi driftwood-dallas.com by: 2. Study of Fast Neutron Radiation Effects in Cold Moderator Materials 83 as ®a burp¯ or ®burping¯. Unlike solid methane, only a little is known about burping of water ice under neutron irradiation, except thermally induced burps in a cold moderator of the NIST reactor [7]. As to methane clathrate, there was no information about its radiation.

    Understanding the biological effects of neutron mixed-beam irradiation used for boron neutron capture therapy (BNCT) is important in order to improve the efficacy of the therapy and to reduce side effects. In the present study, cell viability and DNA Cited by: 8. High neutron flux and high-fluence post-transition corrosion rates were accelerated over out-of-flux post-transition corrosion rates by more than 40 times at °C and more than 30 times at °C. We conclude in large part that the acceleration was caused by irradiation-induced changes to the base driftwood-dallas.com by: 2.

The Effect of Neutron Irradiation and Cold Work on the Strain-Aging Behavior of Zircaloy The strain-aging behavior of annealed Zircaloy-2 in vacuum was studied as a function of deformation temperature, integrated fast-neutron dose, and degree of cold work.

Strain aging occurred in the temperature range to C. Transmission electron Cited by: 7. Effect of neutron irradiation on the room temperature tensile properties of tempered % cold worked Zircaloy material.

However, the per cent changes in mechanical properties as a result of the neutron irradiation were not as large in the cold-worked material as they were in the annealed material (see table 4).Cited by: The effect of fast-neutron damage on the room-temperature tensile properties of zircaloy-2 and zircaloy-4 irradiated at low temperature (1 MeV) and at elevated temperature (– °C) up to × 10 21 n/cm 2 (> 1 MeV) was driftwood-dallas.com irradiation conditions at elevated temperature simulated those of fuel driftwood-dallas.com by: Effects of neutron irradiation on microstructure and properties of Zircaloy.

An historical review is given on the effects of neutron irradiation on the microstructure and properties of Zircaloy. Topics included are basic neutron damage structure, precipitate instabilities, irradiation growth, deformation and mechanical properties, and corrosion.

Experiments were made with Zircaloy-2 tubes containing axial slits. Failure stress at 20 and °C is increased by neutron irradiation: hydride precipitates reduce failure stress at 20 °C but not at °C.

There is evidence that stress applied during irradiation, and neutron dose, affect failure driftwood-dallas.com by: The effects of changes in irradiation temperature on growth strains in cold-worked zircaloy-2 have been studied.

Lowering irradiation temperature produces an initial positive transient strain which is almost fully recovered on raising the temperature driftwood-dallas.com by: It is clearly indicated, from this figure, that the effect of neutron irradiation on Cu is significant.

In irradiated Zircaloy-2, eu, having a strain of about 1% at temperature below K, decreases gradually r Proportional limit. Yield & Ultimate tensile stress test temperature, K Fig.

Synergistic Effects of Neutron Irradiation and Interstitial Nitrogen on Strain Aging in Ferritic Steels. Ferritic steels that are generally used in pressure vessels and various reactor support structures in light water reactors exhibit dynamic strain aging (DSA) resulting in increased work-hardening accompanied by ductility loss.

The effect of neutron irradiation on the tensile deformation behavior of zirconium was examined at room temperature at various strain rates ranging of ×10−4~× 10−2 sec−1. The effect of MeV proton irradiation on the microstructure and mechanical properties of nanocrystalline (nc) nickel was investigated.
