Use of a Semi-Mechanistic Analytical Model to Analyze Radiation Embrittlement of Model Alloys: Cu and P Effects

Strength of Materials Aims and scope

Abstract

We performed analysis of the basic mechanism of radiation embrittlement of steels and weld seams with account of the direct matrix fracture, precipitation and segregation of chemical elements. A model is proposed, which describes matrix fracture due to its neutron bombardment and for 11 model alloys provides an accurate description of the processes of primary embrittlement and re-embrittlement after scheduled heat treatment (annealing). The distinctive features of the proposed model are: a possibility of explaining the embrittlement processes before and after annealing for alloys with low (or zero) Ni content, and its applicability to the analysis of operational behavior of WWER materials.
