Download or read book A Theoretical Model of Accelerated Irradiation Creep at Low Temperatures by Transient Interstitial Absorption written by ML. Grossbeck and published by . This book was released on 1992 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model has been developed using the reaction rate theory of radiation effects to explain experimental results that showed higher than expected values of irradiation creep at low temperatures in the Oak Ridge research reactor (ORR). The customary assumption that the point-defect concentrations are at steady state was not made; rather, the time dependence of the vacancy and interstitial concentrations and the creep rate were explicitly calculated. For temperatures below about 100 to 200°C, the time required for the vacancy concentration to reach steady state exceeds the duration of the experiment. For example, if materials parameters typical of austenitic stainless steel are used, the calculated vacancy transient dose at 100°C is about 100 dpa. At 550°C this transient is over by 10-8 dpa. During the time that the vacancy population remains lower than its steady-state value, dislocation climb is increased since defects of primarily one type (interstitials) are being absorbed. Using the time-dependent point-defect concentrations, the dislocation climb velocity has been calculated as a function of time and a climb-enabled glide creep model has been invoked. The extended transient time for the vacancies leads to high creep rates at low temperatures. In agreement with experimental observations, a minimum in the temperature dependence of creep is predicted at a temperature between 50 and 350°C. The temperature at which the minimum occurs decreases as the irradiation dose increases. Predicted values of creep at 8 dpa are in good agreement with the results of the ORR-MFE-67/7J experiment.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: To study irradiation creep at 400[degrees]C and below, a series of six austenitic stainless steels and two ferritic alloys was irradiated sequentially in two research reactors where the neutron spectrum was tailored to produce a He production rate typical of a fusion device. Irradiation began in the Oak Ridge Research Reactor; and, after an atomic displacement level of 7.4 dpa, the specimens were moved to the High Flux Isotope Reactor for the remainder of the 19 dpa accumulated. Irradiation temperatures of 60, 200, 330, and 400[degrees]C were studied with internally pressurized tubes of type 316 stainless steel, PCA, HT 9, and a series of four laboratory heats of: Fe-13.5Cr-15Ni, Fe-13.5Cr-35Ni, Fe-1 3.5Cr-1 W-0.18Ti, and Fe-16Cr. At 330[degrees]C, irradiation creep was shown to be linear in fluence and stress. There was little or no effect of cold-work on creep under these conditions at all temperatures investigated. The HT9 demonstrated a large deviation from linearity at high stress levels, and a minimum in irradiation creep with increasing stress was observed in the Fe-Cr-Ni ternary alloys.

Available in PDF, EPUB and Kindle. Book excerpt: Measurement of Irradiation-Enhanced Creep in Nuclear Materials covers the proceedings of an international conference organized by the commission of the European communities. The book presents 37 papers that are organized according to the session of the conference. Each session focuses on various topics that relate to the irradiation creep of a specific material, which are ceramic nuclear fuels, graphite, and non-fissile metal and alloys. The text will be of great use for researchers and professionals whose work involves quantifying irradiation creep in nuclear materials.
