Abstract:

DEVELOPMENT OF AN ACCELERATED TEST METHODOLOGY FOR NEAR-THRESHOLD CORROSION FATIGUE TESTING OF WELDED SHIPBUILDING STEELS IS PROPOSED. MIL S-24645 CLASS 3 HSLA STEEL WILL BE USED FOR INITIAL DEMONSTRATION OF THE TECHNIQUE. PRE-TEST MATERIALS CHARACTERISTIZATION WILL INCLUDE MICROSTRUCTURAL FEATURES AND ELECTROCHEMICAL BEHAVIOR. PHASE 1 NEAR-THRESHOLD CORROSION FATIGUE TESTS WILL BE PERFORMED ON BASE METAL SPECIMENS IN SYNTHETIC SEAWATER AT 0 DEG AND 20 DEG F AT THE FREE CORROSION POTENTIAL AND TWO LEVELS OF CATHODIC PROTECTION FOR A SINGLE TEST TEMPERATURE. POST-TEST CHARACTERIZATION OF CORROSION FATIGUE TEST SPECIMENS WILL ATTEMPT TO RELATE OBSERVED MICROSTRUCTURAL FEATURES AND CORROSION PRODUCTS TO TEST VARIABLES AND CORROSION FATIGUE PROCESS MECHANISTICS. SUBMERGED ARC AND PULSED GAS METAL ARC WELDING PROCEDURES WILL BE DEVELOPED TO PROVIDE WELDMENT TEST SPECIMENS SUITABLE FOR ISOSTRUCTURAL CRACK PROPAGATION CORROSION FATIGUE TESTS OF WELD METAL AND HEAT AFFECTED ZONES IN PHASE 2.
