the mechanism of proton irradiation-induced creep in

Irradiation Creep

Irradiation-induced creep behavior is evaluated from the dimensional change due to irradiation with loaded condition. An irradiation-induced creep equation is expressed based on the model, which is the combination of the Maxwell model (steady-state irradiation creep) and the Kelvin model (transient irradiation creep) [15].

The Mechanism of Proton Irradiation

Thus it is critical to understand the mechanism that controls irradiation-induced creep in graphite to be able to predict the integrity of these current and future structural components. This work used POCO Graphite Inc. grade ZXF-5Q, which is an ultra-fine grain graphite.

Healing of Low

Single-walled carbon nanotubes are damaged by low-energy electron and photon irradiation, depending strongly on the diameter. In this study, the formation and healing of the irradiation-induced defects were found to be in competition during irradiation even at room temperature or below. The diameter dependence of the damage can be mainly ascribed to a diameter dependence of the activation

Mechanism Analysis of Proton Irradiation

It was interesting to find out that, although threshold voltage and light output power of Micro-LEDs deteriorated after proton irradiation, a 3-dB bandwidth was greatly improved. In quantitative terms, at the forward current density of 1 kA/cm(2), 3-dB bandwidth increased from original 7.34 to 119.74 MHz when Micro-LED exposed to proton beam with the fluence of 5 x 10(14) p/cm(2).

Challenges to the use of ion irradiation for emulating

2015/5/1Proton irradiation induced stress–free strain in Zr-4, which was consistent with the irradiation-induced growth of recrystallized zirconium alloys. Preferential nucleation of loops near precipitates was observed after proton irradiation, which also occurred during neutron irradiation.

The irradiation-enhanced creep was described by modifying Kachanov-Rabotnov creep damage theory by incorporating the effect of irradiation. Finally the irradiation creep and swelling of type 316 stainless steel at elevated temperatures were predicted by the proposed constitutive equation, and the numerical results were compared with the corresponding experimental results.

Radiation damage induced in Zircaloy

Radiation damage induced in Zircaloy-4 by 2.6 MeV proton irradiation at low doses was studied. Our aim is to emulate the effect of neutron irradiation during early stages of irradiation. X-ray diffraction analysis reveals that the domain size remains constant, while the microstrain increases after irradiation to a dose of 0.017 dpa. The micro-hardness, nano-hardness and Young's modulus are

Observation of Proton Transfer Coupled Spin Transition

An important technique to realize novel electron- and/or proton-based functionalities is to use a proton–electron coupling mechanism. When either a proton or electron is excited, the other one is modulated, producing synergistic functions. However, although compounds with proton-coupled electron transfer have been synthesized, crystalline molecular compounds that exhibit proton-transfer

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 .

Mechanisms of radiation induced creep and growth

1980/5/1Irradiation creep occurs primarily because the applied stress causes the evolving microstructure to respond in an anisotropic fashion to the interstitial and vacancy fluxes. On the other hand, irradiation growth requires the response to be naturally anisotropic in the absence of applied stress. Four fundamental mechanisms of irradiation creep have been conjectured: stress induced

Proton radiation effects on carrier transport in

The real-time IBIC monitoring displayed significant signal degradation from proton radiation at an ultra-high fluence rate (1 10 11 p/cm 2 /s), while the signal collection from irradiation at a high fluence rate (6.25 10 9 p/cm 2 /s) remained stable.

Effects of high

2018/3/28In this paper we explore the effects of 3.5 MeV proton irradiation on Fe(Se,Te) thin films grown on CaF 2.In particular, we carry out an experimental investigation with different irradiation fluences up to 7.30 10 16 cm −2 and different proton implantation depths, in order to clarify whether and to what extent the critical current is enhanced or suppressed, what are the effects of

Observation and possible mechanism of irradiation

The apparent irradiation creep compliances for silicon carbide are substantially smaller than those associated with pure metals and alloys. Microstructural examination suggests that incoherent grain boundaries likely play a major role in determining the primary transient irradiation creep of these materials at high temperatures with a potential additional contribution from basal slip at very

Fundamental Studies of Irradiation

Radiation-induced change in the orientation relationship of pre-existing MX precipitates was observed at 600 . It is believed that this change is associated with the network dislocations formed under irradiation. The underlying mechanism is still not well understood.

Interstitial

Mansur [] developed a model of irradiation creep by climb-enabled glide due to stress-induced preferred absorption of SIAs at dislocations. Raabe [ 6 ] explored all the possible origins for forces on dislocations, and explained how to incorporate osmotic forces due to a vacancy supersaturations into discrete dislocation dynamics (DDD).

Observation and possible mechanism of irradiation

2013/3/1Taken in context of this limited body of evidence on other ceramics and the experience on irradiation creep in metals, SiC appears to be moderately resistant to irradiation-induced creep. Moreover, the mechanism appears to be different than that of metals.

Highly stable tribological performance and

The mechanism of highly stable hydrophobicity and tribological performance was mainly based on a continuous self-healing surface; the stored oil in the pores of PPI can creep to the surface of the material to repair the damage induced by proton irradiation
