The strengthening of embrittled books using gamma radiation

Radiation Physics and Chemistry, 1995
Abstract The embrittlement of papers, manufactured through processes introduced in the mid-19th century, has caused many millions of books to become fragile, even to the point of being unusable. During the 1980s the British Library funded a research programme, carried out at the University of Surrey, to develop a technology which could be used to ...

Radiation embrittlement of low-alloyed Mo alloys

Journal of Nuclear Materials, 1996
Abstract The influence of irradiation in the BOR-60 reactor at 250–1020°C up to fluences 0.013–7.6 × 10 26 n/m 2 ( E > 0.1 MeV) on the mechanical properties of a number of low-alloyed Mo alloys has been studied. Zr, Ti, Ru, B, C were used as alloying elements.

High-temperature radiation-induced embrittlement of nickel

Soviet Atomic Energy, 1983
The reliability and operational lifetime of a number of units in fast-breeder and thermonuclear reactors must largely depend on the degree of the high-temperature radiation-induced embrittlement (HTRE) of materials under neutron irradiation. Many investigators [1-5] associate IITRE with the formation of helium in austenitic chrome--nickel and chrome ...

Theory of radiation embrittlement and recovery of radiation damage in ferritic steels

Philosophical Magazine, 1966
Abstract Utilizing theories developed to explain the behaviour of irradiated face-centred cubic metals, mechanisms are developed to explain neutron embrittlement and subsequent recovery of body-centred cubic metals (including ferritic steels). The proposed micro-mechanism is an adaptation of Seeger's damage theory combined with Makin's saturation ...

The Dependence of Radiation Hardening and Embrittlement on Irradiation Temperature

1996
Assessments of the hardening and embrittlement of pressure vessel steels and welds as a function of neutron dose use trend curves derived from surveillance programmes and accelerated irradiation data. A temperature dependent factor is incorporated for assessing vessel locations operating at different temperatures.

The effect of interstitial impurities on radiation hardening and embrittlement in iron

Acta Metallurgica, 1966
Abstract Previous studies have shown that a transition to brittle behavior at low temperatures is produced in Ferrovac iron when tensile tested at low temperatures after a fast neutron exposure of 2 sx 10 18 nvt at approximately 340°K. This embrittlement phenomenon has not been observed after an identical exposure at 203°K.

Monitoring radiation embrittlement during life extension periods

Nuclear Engineering and Design, 2014
Abstract This paper presents guidelines to monitor the radiation embrittlement of reactor pressure vessels (RPV) during life extension periods (to 60 or 80 years) or for the long term operation of nuclear power plants (NPPs). The guidelines were developed in 2012–2013 by a Task Group of the international project LONGLIFE.

Radiation embrittlement of reactor pressure vessel steels

Nuclear Engineering and Design, 1966
Abstract The problem of radiation embrittlement of reactor pressure vessel steels is considered within the framework of new NRL concepts of fracture analysis and in reference to the primary variables, steel composition, neutron exposure, and exposure temperature.

Microstructural control to improve the resistance to radiation embrittlement in vanadium

Journal of Nuclear Materials, 2005
Abstract In order to improve the resistance to serious radiation embrittlement in refractory metals, a process for microstructural control is presented, with significance of controlling the substance, size, number density and distribution of dispersed particles.

Radiation strengthening and embrittlement in heavy section plate and welds

Nuclear Engineering and Design, 1971
Abstract Fast neutron induced changes in mechanical properties of a 12-in. thick manganese—molybdenum-nickel steel plate and matching submerged arc and electroslag weldments are presented. The increases of strength and notch-impact transition temperature and decreases in ductility are given for several temperatures of irradiation.
