The phenomenon of ductile-to-brittle transition in ferritic steels has been a ubiquitous research challenge
for the last 50 years. The characterization of this problem using the fracture mechanics concept, from the
earliest studies based on the linear-elastic fracture mechanics to the application of the elastic-plastic
fracture mechanics, has become inevitable over time. The fracture toughness is not an intrinsic material
property but depends on geometrical factors (such as the specimen shape, thickness, and surface
roughness), defect type and distribution, loading mode, and environmental conditions. The pronounced
scatter of experimental data on fracture toughness, characteristic of all ferritic steels in the ductile-tobrittle
transition temperature region, necessitated the use of statistical methods for data processing. That
approach, which emerged in the 1970s, can still be found today as the basis for interpreting fracture
toughness data in ductile-to-brittle transition pr...oblems. This paper presents a brief historical overview of
such studies along with the problems that have arisen as a consequence of using fracture mechanics
concepts, such as constraint effects, as an example. In the time-honored research tradition, all the
proposed methods and models, as well as their criticisms, provided the basis for the development of new
approaches to the ductile-to-brittle characterization of ferritic steels. Specifically, these include size
effects and scaling of geometrically similar samples, with the aim of predicting material behavior beyond
experimental limits. Brief outlines of two new approaches are provided in this succinct review. The
criticisms of all presented methods are oriented mostly on the application domain, as well as their
capability to predict fracture toughness, with short overview of their most conspicuous advantages and
disadvantages.
