摘要：
We study the effect of magnetic field on the fracture behavior of the metastable austenitic stainless steels at cryogenic temperatures. Elastic-plastic fracture toughness tests were performed on compact tension specimens in liquid helium at 4 K with and without a magnetic field, and the effect of magnetic field on the cryogenic fracture toughness was discussed. Quantitative phase analysis was also done by magnetic method, and the fracture surfaces were examined by scanning electron microscopy to correlate with the fracture properties.
