Abstract
In liquid helium at 4 K ultra-low carbon steel is known to be brittle. Fracture toughness and ultimate strength measured by the National Institute of Standards and Technology (NIST) are used here to examine the brittle behavior of the SSC yokes. The fracture toughness KIc of the material is used to estimate the maximum allowable length of pre-existing cracks. Tensile properties of the steel at 4 K are compared with maximum tensile stresses obtained from the ANSYS finite element analysis of the DSX201 cross-section.
