    Abstract

    Stretch zones are normally observed on the surface of fracture toughness specimens that break in a ductile manner. However, no stretch zones were observed in the scanning electron microscope on the ductile fracture surfaces of austenitic stainless steels broken in accordance with ASTM E 813 procedure at cryogenic temperatures.
