This paper examines the effect of the parameters of the stucture (grain size, the size and distribution of the particles of the second phase, nonmetallic inclusions, etc.) on the width of the temperature range of the ductile-brittle transition in fcc structural steels. Typical fractographs of the ductile zones on the fracture surfaces of the structural steels are shown. In addition to the large dimples 5-10 ..mu.. in size induced by nonmetallic inclusions (NI) of the type of sulfide, oxide, and nitrides of titanium, the fracture surface contains a large number of fine dimples 1-2 ..mu.. in size induced by cementite-type carbides.
