Abstract

A SYSTEMATIC STUDY OF THE EFFECT OF CONTROLLED RESIDUAL AND INTENTIONAL ALLOYING ADDITONS AND WELDING PREHEAT ON THE WELDABILITY OF MIL-A-12560 ARMOR IS PROPOSED. BASELINE MATERIAL WILL BE COMMERCIAL HEAT OF MIL-A-12560. MULTIPLE LABORATORY SCALE HEATS WILL BE PREPARED WITH CONTROLLED LEVELS OF RESIDUAL AND INTENTIONAL ALLOYING ELEMENTS AND PROCESSED TO PLATE FOR WELDABILITY STUDIES. WITH WELDING PREHEAT AS A VARIABLE, WELDABILITY TESTS TO BE PERFORMED ON THE BASELINE AND EXPERIMENTAL MATERIALS INCLUDE AUTOGENOUS GTAW AND GMAW WELDS, AND IMPLANT TESTS FOR DELAYED CRACKING SUSCEPTIBILITY RESTRAINT AND TESTS AND STRESS RELIEF CRACKING SUSCEPTIBILITY TESTS. INTENSIVE POST-WELD AND POST-TEST CHARACTERIZATION WILL BE USED TO ESTABLISH THE INTERRELATIONSHIPS BETWEEN RESIDUAL ELEMENTS, PREHEAT AND WELDABILITY PERFORMANCE OF MIL-A-12560 ARMOR. THE PROJECT WILL BE PERFORMED BY MSNW, INC. WITH THE ENGINEERING AND TECHNICAL ASSISTANCE OF PHOENIX STEEL AND LEHIGH UNIVERSITY AS SUBCONTRACTORS.
