dose dependence of irradiation hardening of binary

Dose Dependence of Strength After Low-Temperature

Jul 20, 2012 · The minimum dose to the saturation of irradiation hardening was in the range of 0.003 to 0.08 dpa, depending on the category of materials. It was also reaffirmed that there exists a strong relationship between the saturation in irradiation hardening Eeffect of fast-neutron irradiation on mechanical Jul 01, 1982 · The effect of fast-neutron irradiation on the tensile properties and work hardening behaviour of low-carbon Fe (0.02% C), Fe-4% Cr, Fe-9% Cr and Fe-8% Al were investigated up to a fluence of 1.8 × 10 18 ncm 2 (E >;1 MeV) at an irradiation temperature of 40°C.. The room temperature irradiation-induced increase in yield stress showed a (t) 1 2 dependence for Fe, Fe-4% Cr and Fe

Effects of Fe concentration on the ion-irradiation induced

Dec 01, 2016 · Abstract. Understanding alloying effects on the irradiation response of structural materials is pivotal in nuclear engineering. In order to systematically explore the effects of Fe concentration on the irradiation-induced defect evolution and hardening in face-centered cubic Ni-Fe binary solid solution alloys, single crystalline Ni-xFe (x = 060 at%) alloys have been grown and Hardening of FeCu alloys at elevated temperatures by Dec 01, 2001 · Irradiation hardening of Pure-Fe and the other binary alloys increased with increasing in irradiation dose. Especially, Fe-1Mn irradiated over 4.3 x 10(19) n/cm(2) showed significant irradiation IRRADIATION-INDUCED HARDENING OF MARTENSITIC and 90 at.%, is an important feature of the binary Fe-Cr equilibrium phase diagram (see Fig. 1). The phase separation occurs at the nanometer scale and induces hardening of the solid solution. ' has also been observed inmartensitic/ferritic steels by Transmission Electron Microscopy (TEM) after thermal ageing or neutron irradiation at 400-550°C

Irradiation creep in simple binary alloys (Conference

The U.S. Department of Energy's Office of Scientific and Technical Information Mediation of high temperature radiation damage in bcc iron Jan 15, 2020 · A significant irradiation-induced hardness increase was observed for the Fe-Au alloy at a dose of 2.8 dpa while the hardness slightly decreased when the irradiation dose was increased to 8.3 dpa. In contrast, for the Fe-Cu alloy a slight hardening was observed at an irradiation dose of 2.8 dpa followed by a large increase in hardness at an irradiation dose of 8.3 dpa. 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

Neutron Irradiation Hardening of Fe-Based Binary Alloys

Neutron irradiations were carried out at various irradiation doses from 0.3 to 8.5 × 1019 n/cm2 ( > 1.0 MeV) at 290 °C. Irradiation hardening of Fe-1Cu showed a tendency of saturation at a low dose. Irradiation hardening of Pure-Fe and the other binary alloys increased with increasing in irradiation dose. PAPER Vickers hardness change of the Chinese low hardness tester. Hardening was observable at the lowest damage level, and increased with increasing irradiation dose. A power-law correlation of the Vickers hardness with the damage level (HV 0 = 1.49 + 0.76dpa0.31) is proposed.
