Summary

FATIGUE CRACK INITIATION FROM NOTCHES IN AUSTENITIC STAINLESS STEELS HAS BEEN STUDIED USING COMPACT SPECIMENS OF TWO COMMON CRYOGENIC ALLOYS. THE PROCEDURE IS BASED ON A FRACTURE MECHANICS TECHNIQUE. THE EFFECTS OF SOME EXPERIMENTAL VARIABLES INCLUDING NOTCH RADIUS, STRESS LEVEL, SPECIMEN SIZE AND TEST TEMPERATURE (295, 76 AND 4 K) ARE PRESENTED, AND THE FATIGUE CRACK INITIATION RESISTANCES OF AUSTENITIC STEELS ARE COMPARED WITH MARTENSITIC AND FERRITIC/PEARLITIC STEEL DATA AT ROOM TEMPERATURE.
