framework is the Fe-Cr binary alloy. The addition of chromium to iron influences significantly the response to irradiation [1]. For example, it has been shown that swelling in Fe-Cr is about one order of magnitude lower than in pure Fe for the same dose [26]. Even in the absence of irradiation, the Fe-Cr system exhibits a number of Dose dependence of Cu precipitate formation in Fe-Cu High temperature radiation damage in binary bcc Fe alloys containing 1 atomic % Au or Cu due to Fe ion irradiation at 550 °C to a peak dose of 2.8 and 8.3 dpa is studied.

Effects of Transmutation Elements on Neutron Irradiation

4.1 Binary alloys Irradiation hardening ( Hv) of pure W irradiated to 1.54dpa was 100 larger than that of irradiated up to 0.40dpa without remarkable dependence on dpa. Since void lattice was formed in W irradiated to 1.54dpa, it is supposed that irradiation hardening of only irradiated to 0.40dpa at 740 C Fundamentals of radiation materials science :metals and 11.1 Motivation for Using Ion Irradiation as a Surrogate for Neutron Irradiation. 11.2 Review of Aspects of Radiation Damage Relevant to Ion Irradiation. 11.3 Particle Type Dependence of RIS. 11.4 Advantages and Disadvantages of the Various Particle Types. 11.5 Irradiation Parameters for Particle Irradiations. 11.6 Emulation of Neutron Microstructure-dependent rate theory model of radiation May 31, 2021 · @article{osti_1813591, title = {Microstructure-dependent rate theory model of radiation-induced segregation in binary alloys}, author = {Hu, Shenyang and Li, Yulan and Burkes, Douglas and Senor, David J.}, abstractNote = {Conventional rate theory often uses the mean field concept to describe the effect of inhomogeneous microstructures on the evolution of radiation induced defect and solute

Modeling of irradiation hardening of iron after low-dose

Jul 14, 2014 · In experimental studies, the irradiation-hardening behavior of body-centered cubic (bcc), face-centered cubic (fcc) and hexagonal close-packed (hcp) alloys and pure metals has been thoroughly investigated following neutron, spallation proton and ion irradiation at low temperatures by many researchers [1219], which aimed to characterize the dose dependence of irradiation hardening Modeling of irradiation hardening of iron after lowdose Jul 14, 2014 · @article{osti_1143593, title = {Modeling of irradiation hardening of iron after lowdose and lowtemperature neutron irradiation}, author = {Hu, Xunxiang and Xu, Donghua and Byun, Thak Sang and Wirth, Brian D.}, abstractNote = {Irradiation hardening is a prominent low-temperature degradation phenomena in materials, and is characterized both by an irradiation-induced increase in Modeling of irradiation hardening of iron after lowdose Jul 14, 2014 · Irradiation hardening is a prominent low-temperature degradation phenomena in materials, and is characterized both by an irradiation-induced increase in yield strength along with the loss of ductility.

ORNL/LTR-2014/487 A Model of Radiation-induced

In its current version, the code calculates dose dependence of swelling due to the nucleation and growth of an ensemble of cavities (bubbles or voids) under conditions of irradiation or thermal aging, the nucleation and growth of faulted dislocation loops, and the evolution of the network dislocation structure. Phase-field simulation of dose rate effect on the Cu Feb 15, 2021 · Radiation-enhanced precipitation (REP) of Cu in Fe-Cu alloys results in hardening and degradation of the mechanical properties. By combining the CALPHAD-based free energy for phase-field modeling, and radiation-enhanced diffusion (RED) with neutron irradiating energetic particle, the precipitation of Cu in binary Fe-Cu alloys is studied under different dose rates, concentrations, and QuBS Free Full-Text Irradiation Hardening Behavior of Because V4Cr1Ti alloys show significant irradiation hardening and more than 2% Ti addition to V4CrxTi alloys results in a lower irradiation hardening than the V4Cr1Ti alloy, the optimum amount of Ti addition to candidate alloys for structural materials of fusion reactor application should be 2% to avoid surplus irradiation hardening at low-temperature irradiation.

Shuhei Nogami Tohoku University, JapanüSignificant hardening caused by irradiation-induced precipitation in W-26%Re (-phase and -phase) üEffect of Re on the irradiation hardening could be positive and negative, which is dependent on the irradiation conditions. Nemoto et al., JNM, 2000, Hasegawa et al., Title A new approach to evaluate irradiation hardening of The hardness depth profile after self-ion irradiation could intrinsically include three different depth dependent effects:ISE, SSE, and possible DGE. The Fe-1Cu and Fe-1.4Mn after the Fe-ion irradiation showed a composite depth profiles which includes ISE and SSE.
