The effect of precipitate-matrix interface sinks on the growth of voids in the matrix

Abstract: A qualitative discussion of the differing roles played by coherent and incoherent precipitates as point defect sinks is presented. Rate theory is used to obtain semiquantitative estimates of the growth of cavities in the matrix when either type of precipitate is present. Methods for deriving the sink strengths of precipitates of arbitrary shape are developed. In three materials where available microstructural information allows an analysis, precipitates are found to cause only a small relative suppression of c… Show more

“…where j is the geometric factor of precipitates and can be calculated according to the geometric shape and size of the precipitates [61], N p is the number density for the precipitates, and Z p is the capture efficiency of the precipitates and is assumed to be unity for simplicity [62]. It is clear that sink strengths are dependent on the geometry and the number density of the precipitates.…”

“…Облучение образцов нейтронами проводили в реакторе ИВВ-2М при 77-300 K в ин-тервале флюенсов (1,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) Измерения остаточного электросопротивления (при 4,2 К) выполнялись с исполь-зованием стандартного четырехконтактного метода с чувствительностью на уровне 0,01 нОм•см и точностью 0,02 % [14]. Измерение остаточного электросопротивления -чувствительный, точный и экспрессный метод позволяющий отслеживать структурные изменения в металлах и сплавах, следить за изменениями в концентрациях точечных дефектов на уровне ppm.…”
