Abstract:

The mechanisms of fracture of round tensile specimens of two austenitic stainless steels types 304 and 316 and one ferritic steel 2 14 Cr-1 Mo have been studied. These new observations have been combined with published information to construct two types of fracture-mechanism diagram which show the regions of dominance of each mechanism, and summarise the fracture observations between absolute zero and melting point. These diagrams may help in distinguishing between creep-brittle and creep-ductile batches of steel, and in the rational extrapolation of creep-rupture data. Author
