Type of article: Article

Summary

CREEP TESTS AND CONSTANT LOAD RATE TENSILE TESTS AT CRYOGENIC TEMPERATURES WERE CARRIED OUT ON AUSTENITIC STAINLESS STEELS. THE CREEP RATE AT 4 K WAS DECREASED TO A TENTH OF THAT AT 77 K. HOWEVER, AN ABRUPT AND LARGE DEFORMATION OCCURS IN A CONSTANT LOAD RATE TENSILE TEST AT 4 K. THE MAGNITUDE OF THE ABRUPT DEFORMATION DEPENDS ON THE WORK-HARDENING RATE AND THE STABILITY OF THE AUSTENITIC PHASE.
