Contributions of Selected Residual Elements to the Radiation-Embrittlement Sensitivity of Steel Forgings.
Abstract
Residual impurity element content has a major influence on the sensitivity of low-alloy steels to radiation-induced embrittlement. The identification of phosphorus as highly detrimental to irradiation performance has made tin, arsenic, and antimony additional suspect elements. The influence of tin, arsenic, and antimony on elevated-temperature radiation-embrittlement sensitivity was explored using a series of seven experimental NiCrMoV forgings. The forgings represented high and low phosphorus contents in addition to statistical variations of tin, arsenic, and antimony. Assessments of relative radiation sensitivity involved the exposure of Charpy-V specimens at 550F (288C) to a neutron fluence of 3.1X10 to the 19th power n/sq cm > 1 MeV. (Author Modified Abstract)
