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

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | 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. |
