Abstract:
In this paper
the following quantitative and semi-quantitative relationships
were derived experimentally and theoretically. These
relationships are significant in revealing the nature of
ductile-brittle transition and establishing their quantitative
relationships and engineering applications.
Key words:
Steel Ductile-brittle transition
temperature Quantitative relationship
